The sample estimate is exp s where s is the standard deviation of the log-transformed data. To get the average add all the log-transformed results from Step 3 ie 50972 and then divide by the number of samples ie 20 samples in this example. To calculate compounding interest using the geometric mean of an investments return an investor needs to first calculate the interest in year one which is 10000 multiplied by 10 or 1000.
This is equivalent to raising 19500 to the 15-th power.
Can be used for calculating or creating new math problems. This follows from the fact that the variance and mean both obey this principle. The average of the 20 log- transformed results in the example data set is 2549. The formula is equivalent to.
