2.64 FAQ-616 What are the different methods to calculate average value in Origin?
Last Update: 10/2/2015
There are several ways to obtain an average value or average dataset.
Quick Stats Reported to the Status Bar
When you select a range of cells in the worksheet a few quick statistics, including the average value, are reported to the Status Bar at the bottom of the Origin workspace. Right-click to choose reported statistics from a shortcut menu, or copy them to the Clipboard. For more information see The Status Bar.
The Average Value of a Column
The average value for a particular column can be obtained by selecting Statistics:Descriptive Statistics:Statistics on Columns from the Origin menu. Once calculated, Origin reports the results to a new worksheet. The average for each selected column is placed into a separate cell in the Mean column.
For details, see The Statistics on Columns Dialog Box.
The Average Value Across Rows
To obtain the average value for a series of rows of data in a worksheet, select Statistics:Descriptive Statistics:Statistics on Rows. By default, Origin places the results in new columns in the original worksheet immediately to the right of the selected data.
For details, see The Statistics on Rows Dialog Box.
The Average Value Using the Mean Function
Define a dataset (e.g. column A) and its average value will be returned by the LabTalk function Mean(). For example:
The Average Value for a Portion (Region-of-Interest) of a Data Plot

To access the data, double-click on the average curve to open the Plot Details dialog box and click on the Worksheet button.
