Overview

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

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

	Value/Description	Example
Formula Name:	Mean	Statistics.Mean ("Series1")
Parameters:	inputSeriesName: The name of the Series object that stores the data for which an average is required.	Statistics.Mean("Series1")
Return:	A double that represents the average of all the data points in the given series.	-

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

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.
