=VARP(number1, [number2], [number3], ...[number255])
=VARP(A2:A11)
The VARP function is used to calculate the variance of a population of data. In the example above, this function will return the variance of the breaking strengths of all the tools, assuming that 10 tools are produced.
=VAR(A2:A11)
The VAR function is used to calculate the variance of a sample of data. In the example above, the function will return the variance of the breaking strengths of all the tools, assuming that only a sample of the population is used.
=VARP(A2:A11,B2:B11)
The VARP function can also be used to calculate the variance of multiple sets of data. For example, if there are two sets of data in columns A and B, the VARP function can be used to calculate the variance of both sets of data.
=VARP(A2:A11)
The VARP function can also be used with an array of data. In this example, the function will return the variance of the data in cells A2 through A11.
The VARP function calculates the population variance, while the VAR function calculates the sample variance. VARPA also takes into account logical values and text when determining the variance.
