Overview

This formula returns the average, or mean, of data stored in a data series.

Applying the Formula

All statistical formulas are calculated using the Statistics class, and the following table describes how to use its Mean method to get an average.

Note
Make sure that all data points have their XValue property set, and that their series'  XValueIndexed property has been set to false.

Statistical Interpretation

The average, or mean, is the sum of all values divided by the number of values.

Please note that it is the first Y value (Y1) of all data points that are used to calculate the mean.
