#### How to calculate logarithmic average in Excel

Logarithmic average, also known as the geometric mean, can be calculated in Excel by using the geometric mean formula.

The formula for logarithmic average is:

Logarithmic average = exp (sum (ln (x))/n)

where x is the data set, n is the number of data points, exp is the exponential function, and ln is the natural logarithm function.

To calculate logarithmic average in Excel, you need to use the EXP, SUM, LN, and COUNT functions. Here’s how to calculate logarithmic average in Excel:

- Enter the data set in a column.
- In a separate cell, enter the formula =EXP(SUM(LN(A2:A7))/COUNT(A2:A7)), where A2:A7 is the range of cells containing the data set.
- Press Enter to calculate the logarithmic average.

Explanation:

The formula uses the EXP and SUM functions to calculate the exponential of the sum of the natural logarithms of the data set, divided by the count of the data set. The natural logarithm is used to convert the product of the data set to a sum, which can then be averaged. The exponential of the average is then calculated to give the geometric mean.

In summary, to calculate logarithmic average in Excel, you need to use the geometric mean formula and the EXP, SUM, and COUNT functions. With these functions, you can easily calculate logarithmic average in Excel.
