- The geometric mean return formula is used to calculate the average rate per period on an investment that is compounded over multiple periods. The geometric mean return may also be referred to as the geometric average return
- Geometric mean return is a method that allows us to calculate the average rate of return on investment (or portfolio). The main advantage of this method is the fact, that we don't have to know the original principal amount, geometric mean return method is completely focused on the rate of return

** The geometric average return formula (also known as geometric mean return) is a way to calculate the average rate of return on an investment that is compounded over multiple periods**. Put simply, the geometric average return takes into account the compound interest over the number of periods The **geometric** **mean** is the average growth of an investment computed by multiplying n variables and then taking the nth - root. In other words, it is the average **return** **of** an investment over time, a metric used to evaluate the performance of a single investment or an investment portfoli The result gives a geometric average annual return of -20.08%. The result using the geometric average is a lot worse than the 12% arithmetic average we calculated earlier, and unfortunately, it is.. Geometric Mean Return. To calculate the geometric mean return, we follow the steps outlined below: First, add 1 to each return. The trick is to avoid problems posed by negative values. Multiply all the returns in the sequence. Raise the product to the power of 1 divided by the number of returns 'n'. Finally, subtract 1 from the final result; Example: Geometric mean

In statistical and business terms, a geometric average return (a.k.a. geometric mean return) represents the rate of return on investment per year, averaged over a specified time period. When assets increase in value year on year, a geometric average return will let you know what the increase in value would look like if represented by an annual interest rate Geometric Average Return is the average rate of return on an investment which is held for multiple periods such that any income is compounded. In other words, the geometric average return incorporate the compounding nature of an investment

You will see notes for these..

Synonyms: geometric mean, geometric average, compounded rate of return. For context, it is important to realize that the calculation of rate of return is more complex than it seems on the surface, particularly when you consider all corporate actions such as splits, special dividends and spin-offs. As a result most practitioners utilize data providers to make these calculations. This still.

The geometric average rate of return was 5%. Over 4 years, this translates into an overall return of: = The geometric mean can be used to calculate average rates of return in finances or show how much something has grown over a specific period of time. In order to find the geometric mean, multiply all of the values together before taking the n th root, where n equals the total number of values in the set * This is also commonly known the arithmetic mean return*. b. Geometric return. Geometric returns, on the other hand, refer to a specific period of time and the order of returns matters. To account for this, returns are multiplied, instead of added. Here, compounding is incorporated and you might see daily, monthly or annual periods linked together. Here we add 1 to the first period return, in. Geometric mean is the average rate of return of a set of values calculated using the products of the terms. The general formula for the geometric mean of n numbers is the nth root of their product. For example: = GEOMEAN (4, 9) // returns 6. The long-hand calculation would be: = (4 * 9) ^ (1 / 2) = (36) ^ (1 / 2) = 6. The arithmetic mean would be (4 + 9)/2 = 6.5. In the example shown, GEOMEAN. If you calculate this geometric mean you get approximately 1.283, so the average rate of return is about 28% (not 30% which is what the arithmetic mean of 10%, 60%, and 20% would give you). Any time you have a number of factors contributing to a product, and you want to find the average factor, the answer is the geometric mean

The geometric mean return on an investment is also referred to as the time weighted rate of return and is used by a wide number of financial professionals. To use the online Geometric Mean Calculator all you have to do is enter in the annual returns separated by a comma, the initial investment amount, and then press calculate Geometric mean return Also called the time-weighted rate of return, a measure of the compound rate of growth of the initial portfolio market value during the evaluation period, assuming that all cash distributions are reinvested in the portfolio. It is computed by taking the geometric average of the portfolio subperiod returns The geometric mean is more appropriate than the arithmetic mean for describing proportional growth, both exponential growth (constant proportional growth) and varying growth; in business the geometric mean of growth rates is known as the compound annual growth rate (CAGR). The geometric mean of growth over periods yields the equivalent constant growth rate that would yield the same final amount Definition of 'Geometric Average Return'. Definition: Popularly called Geometric Mean Return, it is primarily used for investments that are compounded. It is used to calculate average rate per period on investments that are compounded over multiple periods

* The geometric average proves to be ideal when analyzing average historical returns*. What sets the geometric mean Geometric Mean The geometric mean is the average growth of an investment computed by multiplying n variables and then taking the n square root. It is the average return apart is that it assumes the actual value invested. Computation only pays attention to the return values and. The geometric mean is 1.0256 which equals 2.56% average growth per year. Our geometric mean calculator handles this automatically, so there is no need to do the above transformations manually. You can also enter the numbers with %, like 2% 10% -10% 8% and will deal with that as well (it simply strips the %) Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube geometric mean return: translation Also called the time-weighted rate of return, a measure of the compound rate of growth of the initial portfolio market value during the evaluation period, assuming that all cash distributions are reinvested in the portfolio. It is computed by taking the geometric average of the portfolio subperiod returns

Geometric mean is the average rate of return of a set of values calculated using the products of the terms. The general formula for the geometric mean of n numbers is the nth root of their product. For example: = GEOMEAN(4,9) // returns 6. The long-hand calculation would be: = (4 * 9) ^ (1 / 2) = (36) ^ (1 / 2) = 6 Compute the geometric mean rate of return for U.S T-Bills. T-Bills: T-bills are debt instruments sold by the U.S. Treasury Department in order to finance some of the government's expenses The optimal geometric mean return is an important property of an asset. As a derivative of the underlying asset, the option also has this property. In this paper, we show that the optimal geometric mean returns of a stock and its option are the same from Kelly criterion. It is proved by using binomial option pricing model and continuous stochastic models with self-financing assumption The geometric mean is more accurate than the arithmetic mean because it accounts for compounding: Geometric Mean = [ (1+ TR 1) (1+ TR 2) (1+ TR n)] 1/n - 1 TR = Total Return So the geometric mean for the above $10 stock would be √ (1 + 1) × (1 -.5) - 1 = √ 2 ×.5 - 1 = 1 - 1 = 0%

- Geometric Mean Return Geometric mean return is the compounded rate of return earned on an investment. Geometric mean return = [ (1 + R i1) * (1 + R i2) * .* (1 + R iT)] - 1 Assume you have a stock A which returns 10%, 20% and 30% in years 1, 2, and 3 respectively
- Say I'm given I set of monthly returns over 10 years on a monthly basis. What is the correct way to find the geometric returns of this data? I ask because a classmate and I are on different sides of the coin. I found the cumulative returns of each year, then found the geometric mean of the 10 years. He found the cumulative returns of the entire.
- The geometric mean is calculated relative to the total (100%) = ((1+.2)* (1-.05))^ (1/2)-1= 6.77% This means that an investment with a constant return of 6.77% each period is equivalent to your investment. You invest 10
- Plugging the geometric mean of the interest rates into our compound interest formula: Total interest earned = $100,000 * (1.0648⁵ - 1) = $36,883.70 Interest + principal = $36,883.70 + 100,000 = $136,883.70 Final total = $136,883.70 exactly the same as the long method above. That's more like it
- Assume equally likely returns of 25% and -20%, the arithmetic mean is 2.5%. If however the geometric mean is used, the answer is 0: (1+25/100) x (1-20/100) -1. To further amplify this point.

Setting the allowed rate of return at the geometric mean instead would produce a compound rate of return over a number of years that was well below that geometric mean. This point is emphasized by a 1974 paper by Marshall Blume. 49 That paper asks how to forecast the achieved return on a portfolio after H years based on a past series of returns over T years, with T greater than H FINDING GEOMETRIC MEANS WITHIN AN OBSERVATION: GEOMEAN()/GEOMEANZ() Finding the geometric mean of a series of data points is very easy using the GEOMEAN function with the following syntax: GEOMEAN(argument<,argument,>) GEOMEAN will return the geometric mean of all non-missing values, and will fuzz any values that ar The geometric mean will provide us with the answer to the question, what is the average rate of return: 16 percent. The arithmetic mean of these three numbers is 23.6 percent

The geometric mean is also referred as the compounded annual growth rate, as the average rate of return values are calculated based on the product of the terms. It comes from the arithmetic mean but uses multiplication and roots. Investors find the geometric mean value for their investments to get compounding return values. This geometric mean calculator is capable of processing any range of inputs in uniformly same time The geometric mean will provide us with the answer to the question, what is the average rate of return: 16 percent. The arithmetic mean of these three numbers is 23.6 percent. The reason for this difference, 16 versus 23.6, is that the arithmetic mean is additive and thus does not account for the interest on the interest, compound interest, embedded in the investment growth process. The same. Arithmetic and Geometric Averages. Lets say we have 6 year sequence of investment returns as follows: +30%, -20%, +30%, -20%, +30%, and -20%. An arithmetic average is simply the sum of all the terms (numbers) divided by the count of that sequence

Essentially, the time-weighted rate of return is the geometric mean of the holding period returns of the respective sub-periods involved. Time-weighted Rate of Return Formula When working out time-weighted measurements, we break down the total investment period into many sub-periods * Geometric mean for rate of return I'm trying to calculate an annualized rate of return*. I have a column of return percentages and i need a formula that will add 1 to all of the values then plug into the GEOMEAN function. Col D 1 32.08% 2 76.92% 3 19.29% 4 9.05%.

- g that all.
- The zero percent that you really got is the geometric mean, also called the annualized return, or the CAGR for Compound Annual Growth Rate. Volatile investments are frequently stated in terms of the simple average, rather than the CAGR that you actually get. (Bad news: the CAGR is smaller.
- In summary, the key takeaway is that the Geometric Mean (or Time Weighted RR), is more accurate for returns than the arithmetic mean. Internal Rate of Return (IRR), or Money Weighted Rate of Return..
- For financial investment return calculations, the geometric mean is calculated on the decimal multiplier equivalent values, not percent values (i.e., a 6% increase becomes 1.06; a 3% decline is transformed to 0.97. Just follow the steps outlined in the section below titled Calculating Geometric Means with Negative Values)
- The arithmetic mean of these returns is 13.9% per annum. The geometric mean can be calculated from the index levels of 1000 on 31 December 1979 and 37,134.5 on 31 December 2012 and is 11.6% per annum

- The geometric mean is an appropriate measure to use for averaging rates. For example, consider a stock portfolio that began with a value of $1,000 and had annual returns of 13%, 22%, 12%, -5%, and -13%.The table below shows the value after each of the five years
- The geometric mean return will be less than the expected return (sometimes termed the arithmeticmean), as long as there is some variation in returns. Moreover, the difference between the geometric and arithmetic means will be greater, th
- rate of return, which exceeds the geometric mean by (1/2)&2. After an investment horizon of H peri-ods, the unbiased forecast of future portfolio value is, therefore, 2 E(St+H) = Ste(p+1/2 )H (2) Equation 2 is the basis of the textbook rule that to forecast future value, one should compound for-ward at the mean arithmetic return

The geometric mean of returns. This means the annualized return on the portfolio had been negative at 13.40%. The investment position after two years is as below: Therefore, the Geometric mean shows the true picture of investment that there is a loss in investment with an annualized negative return of -13.40%. Since the return in each year impacts the absolute return in the next year, a. The rates of return are: 18% in the first year, 5% in the second year. When working with the returns to risky assets, it is sometimes helpful to determine their mean or average return. Investors find the geometric mean value for their investments to get compounding return values. The geometr Geometric Returns. One problem with arithmetic mean is that it assumes the returns on the investment made at the beginning of each period. So, for each period the beginning investment amount is assumed to be the same. It ignores the compounding effect of investment returns made in the previous years. Using arithmetic returns, our measure can be majorly flawed. Consider an investment of $100 at. Geometric mean can be used to calculate average rate of return with variable rates. Excel RRI Function The Excel RRI function returns an equivalent interest rate for the growth of an investment This is known as the geometric mean, or the geometric average return. The geometric average represents the average annual growth rate that would have generated an equivalent amount of final wealth with a straight line series of returns, even though the returns didn't actually occur in a straight line

Arithmetic Return Formula. The Arithmetic Return is the simplest way of calculating the rate of return on an investment. To calculate it, you need the amount of growth, which is simply the final value `V_f` minus the initial value `V_i`. Then you just divide the amount of growth by the initial amount, as shown in the following formula: `R = (V_f - V_i) / V_i xx 100%` This value is normally. Possible Rate of Returns Probability -0.60 0.05 -0.30 0.2 Rate of return is a measurement—a number calculated from more basic primitive data. The calculation of rates of return is the crucial first step in performance evalua-tion: Without accurate rates of return, we can make no further progress in analyzing performance. The purpose of this reading is to define the various forms of return On this page is a compound annual growth rate calculator, also known as CAGR. It takes a final dollar amount as input, along with a time frame and starting amount. The tool automatically calculates the average return per year (or period) as a geometric mean. The Compound Annual Growth Rate Calculato In simple words, An annualized rate of return is evaluated as an equivalent amount of annual return an investor is entitled to receive over a stipulated period. It is computed based on time-weight, and these are scaled down to a period of twelve months, which allows investors to compare the return on assets over a particular time

The Time-Weighted Return (also called the Geometric Average Return) is a way of calculating the rate of return for an investment when there are deposits and withdrawals (cash flows) during the period. You often want to exclude these cash flows so that we can find out how well the underlying investment has performed. To calculate the time weighted return for a particular period, the period in. If we follow these three steps, the result is an average annual rate of return of 22% (after rounding) calculated as a geometric mean. The rates of return for various mutual funds available on the web should provide you with the geometric mean. But the Web is not very helpful at the client's kitchen table. Most business calculators will allow you to quickly calculate the geometric mean through. In Mathematics, the Geometric Mean It is used to calculate the annual return on the portfolio. It is used in finance to find the average growth rates which are also referred to the compounded annual growth rate. It is also used in studies like cell division and bacterial growth etc. Geometric Mean Examples . Here you are provided with geometric mean examples as follows. Question 1 : Find. Geometric mean return, also referred to as compounded annual growth rate, or time weighted rate of return need the above mentioned factors. The reference is also made with geometric average return. So, the first factor is the rate of returns of each of the periods and they are to be mentioned in the form of percentage. The second factor is the.

The effective annual rate is 10.47%. This means that a dollar invested at 10.00% with monthly compounding will yield the same amount in one year as a dollar invested at 10.47% with no monthly compounding. The continuously compounded rate can be solved using the cumulative return with the formula below. Returns can also be averaged using either the arithmetic or geometric mean. When presenting. Based on the literature [119], [120] a simple arithmetic was used versus the geometric mean to compute the annualized average rate of return from monthly returns 5 data over the three year time. performance with the mean compound return of their funds. For both reasons, then, a potential plausible goal for portfolio managers to adopt would be to grow the capital entrusted to them at the fastest possible rate; that is, to maximize the geometric mean return of their portfolios. At least two questions arise naturally from this discussion. The **geometric** **mean** real **rate** **of** **return** for the Blackwell Publishers Ltd, 1996 . 160 Ian Cooper same period was 7.0%. I A similar difference arises if one uses arithmetic or **geometric** average estimates of the risk premium. There are three possible problems with the use of the arithmetic **mean** or **geometric** **mean** as estimates of the true expected **return**. These correspond to the three assumptions.

- Geometric mean = [ (1+0.0909) * (1-0.0417) * (1+0.0174) * (1-0.0043) ] 1/4 - 1 Geometric mean = 1.45%; Mean Example - #4. Below is the sample of 5 children who are aging 10 years old and their height data is given.

- If you were a mean-variance investor deciding between the risk-free rate and the strategy, you would estimate the mean and variance of the log returns, project it to the investor's horizon, and convert the normal to lognormal to obtain the arithmetic returns. So if you were calculating a Sharpe ratio that is consistent with the way it was originated in financial theory, i.e. the slope of the.
- ing the present values of promised benefit payments payable over long periods). In particular, the ASOP acknowledges the distinction between assumptions that reflect arithmetic versus geometric average returns (Section 3.8.3[j]). Arithmetic averages generally exceed geometric averages, but.
- If we calculate Geometric mean/average for the above example; Geometric mean = (1.15 * 0.6 * 1.3) ^1/3 , So by solving, geometric or compound average annual rate of return on your investment comes to negative 3.55% (-3.55%)
- This bias does not necessarily disappear even if the sample average return is itself an unbiased estimator of the true mean, the average is computed from a long data series, and returns are generated according to a stable distribution. In contrast, forecasts obtained by compounding at the geometric average will generally be biased downward. The biases are empirically significant. For.

Metal Geometric mean rate of return . Platinum 14.68%. Gold 15.38 %. Silver 19.39 %. Compute the geometric mean rate of return per year for the stock indices from 2009 through 2012. For stock exchange A, the geometric mean rate of return for the four-year period 2009-2012 was _____ % Compound rates. The main use of geometric means you're likely to find described on the internet is calculating average compound interest, inflation, or investment returns. In these sorts of cases, you have a series of ratios that act multiplicatively: each one scales the previous total, in sequence. The geometric mean produces the most commonly sought-after summary here: the rate that all. * As with the simple geometric mean, if the ValueColumn in your table contains a rate of growth or decay (for example, annual investment returns of 4%, 8%, -15%, and 6%), then we need to adjust these rates by adding one to each item, thus transforming the values into the factors that would be used in determining the end result of the growth or decay*. The generic SQL statement then becomes. If you or any investor wants to compute the compounding interest of 25years using the geometric mean of an investment's return, you need to first calculate the interest in year one, then add the interest rate to next year principal's amount and the chain will follow until 25years. Suppose you want to calculate a principal amount of Rs. 10,000 on 10% interest rate. Then, for year one, you.

Geometric Average Return or the compound annual return is the calculation of the average return of investment from beginning up to now. It simply means the average return over investment life from the first year. It is mostly used for investments that are compound over multiple periods. We simply group similar investments into a portfolio and evaluate their performance together. It focuses on. Geometric Mean ≈ 1.3276. If we find the geometric mean of 1.2, 1.3 and 1.5, we get 1.3276. This should be interpreted as the mean rate of growth of the bacteria over the period of 3 hours, which means if the strain of bacteria grew by 32.76% uniformly over the 3 hour period, then starting with 100 bacteria, it would reach 234 bacteria in 3. Geometric mean return on investment is also known as the time weighted rate of return. Financial professionals usually use it when they measure investment performance over a number of periods. Arithmetic mean (also called simple average) is not used for this purpose because it does not take into account the compounding of interest. Arithmetic mean therefore does not provide a good measure of. Referring to Table 3-8, calculate the geometric mean rate of return per year for Company C. Q 134. Referring to Table 3-8, calculate the geometric mean rate of return per year for Company D. Q 135. Referring to Table 3-9, what is the mean for this population of the five largest bond funds? Explore all questions. The 'true' economic rate of return is what most people's understanding of it would be. People refer to it as the Compound Annual Growth rate (CAGR), Effective Annual rate, Annual Equivalent rate, Internal Rate of Return (IRR), discount rate, geometric mean, or Annualized Compound rate..Essentially these all refer to the same concept

It makes a lot of sense to use the geometric mean of the Ri to do that because GeoMean(R) = Exp(Mean(r)*T), which is the ratio you would get from the average rate of change. That is the logic, I believe, behind the use of the geometric mean in that context As clearly illustrated, the geometric mean is the rate of return that correctly expresses the growth of $10,000. The arithmetic mean dramatically overstates the actual annualized growth rate of. Geometric Mean. The geometric mean is an average that is useful for data series of positive numbers that are better interpreted according to their product, such as growth rate. It's calculated by: \[\bar{x} = \sqrt[n]{x_1x_2x_3...x_n}\] Let's calculate the geometric mean of a series of single-period return Geometric Mean: two periods. R. 1, R 2 . rates of return in decimal formGeometric mean: the constant return R. g. in each period that produces the same terminal wealth at the end of period 2 as do the actual returns for the two periods, that is, (1+ R. g)(1+ R g) = (1+R 1)(1+R 2), so (1+ R. g)2 = (1+R 1)(1+R 2); solving for R. g Author: Dept of Statistics Created Date: 08/30/2000 02:32:54. return stream, the geometric mean is equal to 111121+=+ ×+ ××+RG R R RT()[()][()] [()]T where R(G) = the return for the geometric mean R(1), R(2), R(T) = the returns to asset X in periods 1, 2, all the way to period T T = the number of periods over which we calculate the geometric mean T means that we take the Tth root of our compound return stream to determine R(G) Using the data in.

The Geometric Mean is also known as the compounded annual growth rate. The example below shows how to use the geometric mean to calculate the return on a portfolio. It is important to understand that the geometric average should be used instead of the arithmetic mean in the context of a time-series calculation The average rate of return is not found by calculating the arithmetic mean, which would imply that in the first year your investment was multiplied (not added to) by 2 (1+100%); and that in the second year it was multiplied by 0.5 (1-50%)). The true average rate of return is found by calculating the geometric mean of these two numbers, which equals 1, revealing that your investment earned no. mal distribution with mean µt/n and variance σ2t/n. Thus we can approximate geometric BM over the ﬁxed time interval (0,t] by the BLM if we appoximate the lognormal L i by the simple Y i. To do so we will just match the mean and variance so as to produce appropriate values for u,d,p: Find u,d,p such that E(Y) = E(L) and Var(Y) = Var(L. An example of the geometric mean: The growth rate of gold. Let's apply the ideas in the preceding section. Suppose that you bought $1000 of gold on Jan 1, 2010. The following table gives the yearly rate of return for gold during the years 2010-2018, along with the value of the $1000 investment at the end of each year. According to the table, the value of the investment after 9 years is $1160. First, that the geometric mean return is the average rate at which an invested capital evolved over time. Of course you were getting different returns over time, year after year you got positive returns, negative returns, high returns and low returns. But if you actually think in terms of the mean annual evolution of your capital, in the case of the world market, it evolved at 7.7%, so it's.

During the past five years you owned two stocks that had the following annual rates of return: Year Stock A Stock B 1 0.18 0.09 2 0.6 0.04 3 -0.15 -0.11 4 -0.01 0.04 5 0.11 0.05 a) compute the arithmetic annual rate of The Geometric Mean is useful when we want to compare things with very different properties. Example: you want to buy a new camera. One camera has a zoom of 200 and gets an 8 in reviews, The other has a zoom of 250 and gets a 6 in reviews. Comparing using the usual arithmetic mean gives (200+8)/2 = 104 vs (250+6)/2 = 128. The zoom is such a big number that the user rating gets lost. But the. For financial investment return calculations, the geometric mean is calculated on the decimal multiplier equivalent values, not percent values (i.e., a 6% increase becomes 1.06; a 3% decline is transformed to 0.97. Just follow the steps outlined in the section below titled Calculating Geometric Means with Negative Values). The equation is also flipped around when calculating the financial rate.

The arithmetic mean on this portfolio would have been 23%. As you can see, geometric return is lower than the arithmetic return, and is a better method for aggregating returns over multiple holding periods. We can say that geometric mean is a more suitable method for aggregating returns over a period of time expected annual compounded rate of return is µp - 0.5σ p 2, or 7.50% - [.5 (10%)2], which is 7.00 percent. Just as the geometric mean is less than the arithmetic mean when the returns are not identical, the compounded return is lower than the expected annual return because of volatility

Return to MaxValue Home Page. Geometric Mean and Harmonic Mean. A statistic is simply a number that describes something about a population (i.e., probability density function) or data. Mainly, statistics describe where the distribution is located or something about its shape. One class of statistics is central measures which describe where a distribution is located or centered on the x-axis. The rate of return on an investment that is calculated by taking the total cash inflow over the life of the investment and dividing it by the number of years in the life of the investment. The average rate of return does not guarantee that the cash inflows are the same in a given year; it simply guarantees that the return averages out to the average rate

Geometric means work here to help you calculate the growth rate because cell growth is a nonlinear process, so arithmetic means would not be helpful. To calculate the mean growth rate, simply calculate the geometric mean of the growth rates: ∛(2.7*2.59*2.29) = ∛(16.02) = 2.52 or 252% When one is creating a client plan, and using 'asset allocations', in the process, the underlying assumptions, about long-term 'mean' returns, can be either arithmetic values, or geometric values and - with reference to the above, it will be the case, if one is using 'arithmetic' mean values, that one will be consistently 'overestimating' the client's actual return, for the same reason that. How to figure out geometric mean rate of return for 10% and 40%. Answer by Guest The central number in a geometric progression (e.g., 9 in 3, 9, 27 ), also calculable as the n th root of a product of n numbers. websight from googl You can freely add up or subtract values on the log-return scale, like log-interest rates or log-inflation rates. Whereas the arithmetic mean of (non-log) returns is simply meaningless: A stock with returns -3% and +3% would have 0% on average, when in fact the stock has declined in price? The correct approach on direct price-returns would be to take a different mean (e.g. geometric) to get a. scipy stats geometric mean returns NaN. Ask Question Asked 9 years, 9 months ago. Active 9 years, 9 months ago. Viewed 7k times 4. I am using scipy's gmean() function to determine the geometric mean of a numpy array that contains voltage outputs. The range of the numbers is between -80.0 and 30.0. Currently, the numpy array is two dimensional, giving the voltage for two different measurements.
