Statistics on Selected Range
Origin provides some quick ways to obtain basic statistics on a selected range of worksheet cells, or data plot(s) in a graph.
Status Bar
Statistics, Data Selection
Select a range of cells in a worksheet. Note that the selection can include cells from one or more columns, and you can use the CTRL key to select noncontiguous groups of cells. Statistics, Report to Status Bar
Basic statistics (average, sum, count, min, max) for your selected data will be displayed in the status bar. Right click on the status bar to customize what quantities to display.
Command or Script Window
Statistics, Report to Script/Command Window
 Select a range of cells in a worksheet, or click and select a group of data plots or an individual data plot in a graph.
 Open the Command Window or the Script Window from the Windows menu, and type one of these commands, then press ENTER:
stats
moments
quantiles
With the Command Window, the results are typed out below the command line. With the Script Window, you will need to issue an additional command to return your results:
stats;
stats.=;
