Estimates variance based on a sample.
Syntax
VAR(number1,number2, ...)
Number1,number2, ... are 1 to 30 number arguments corresponding to a sample of a population.
Remarks
Example
Suppose 10 tools stamped from the same machine during a production run are collected as a random sample and measured for breaking strength. The sample values (1345, 1301, 1368, 1322, 1310, 1370, 1318, 1350, 1303, 1299) are stored in A2:E3, respectively. VAR estimates the variance for the breaking strength of the tools.
VAR(A2:E3)
equals 754.3
