I just had this problem myself. A simple solution, not 'the solution' (as i believe you can pay for this function to be added to excel), is as follows: (NB. This can be checked with reference to the GEOMEAN function).
e.g. your data is in column A (A3-A33)
in cell B3 type =LN(A3) (i.e. the natural log)
copy and paste down to B33.
In B34, calculate the standard deviation of the loged numbers i.e. =STDEV(B3:B33)
In A34 type =EXP(B34) This is your geometric standard deviation!!
You can check this method with ref. to the GEOMEAN function.
Take the mean of column B. i.e. in cell B35 type =average(B3:B33)
In cell A34 type =EXP(B34).
This should returen the same answer as =GEOMEAN(A3:A33)
There is an error in the above mentioned function which is:
//In B34, calculate the standard deviation of the loged numbers i.e. =STDEV(B3:B33)
Here do not calculate the STDEV(b3:b33) instead, calculate the =AVG(b3:b33)
The command to find the sample standard deviation, which is SX, in Excel is:
=STDEV(VALUES)
The command to find the population standard deviation in Excel is:
=STDEVP(VALUES)

How do you do standard deviation on Microsoft Excel?
Use the STDEV() function.
How do you calculate the standard deviation of the mean using Excel?
=stdev(...) will return the N-1 weighted sample standard deviation. =stdevp(...) will return the N weighted population standard deviation.
How do you calculate sample standard deviation?
Here's how you do it in Excel: use the function =STDEV(<range with data>). That function calculates standard deviation for a sample.
How do you calcuate standard deviation?
A worked out example is shown in the related link. There are a number of calculators that do this automatically. Also, the Excel program (and most other spreadsheet programs) include a standard deviation function. In Excel, it is +stdev(a1:a10) for a list of numbers from a1 to a10.
How do you calculate two standard deviations of the mean?
See the related links on how to calculate standard deviation. If there are more than a dozen data points, it is tedious to calculate by hand. Use excel or an online calculator. To get 2 standard deviations, multiply the calculated std deviation by 2.
What is the standard deviation of a sample of 35 25 36 42 37?
Putting the data into excel, the std dev for the sample is 6.20
In Excel order of precedence detemines what?
The order in which Excel will perform calculations.
In Excel what is used to perform mathematical problems?
yes you can do math in excel, it is very easy.
What is the relationship between Microsoft Excel and calculations?
The main reason for Excel is to perform calculations.
Find the geometric mean 10 and 40?
Used the GEOMEAN function on Excel and the answer it gave was 20.
How can you perform calculations on Microsoft Excel?
See excel help file it's very easy
What is sharpe ratio?
The Sharpe Ratio is a financial benchmark used to judge how effectively an investment uses risk to get return. It's equal to (investment return - risk free return)/(standard deviation of investment returns). Standard deviation is used as a proxy for risk (but this inherently assumes that returns are normally distributed, which is not always the case). See the related link for an Excel spreadsheet that helps you calculate the Sharpe Ratio, and other limitations.
