Calculate the sample variance of the following set of numbers:7, 9, 14.

The formula for sample variance is

sample variance=?(x?x¯)2n?1

where x represents the individual datavalues, x¯ is the sample mean, n is the samplesize, and ? means sum up the values. Thedifferences x?x¯ are called deviations. Enter all eightresponses as integers.

mean =

deviation of value 1 =

deviation of value 2 =

deviation of value 3 =

square of the deviation of value 1 =

square of the deviation of value 2 =

square of the deviation of value 3 =

variance =
