s2, is the sum of squared deviations from the mean divided by n − 1.
s2,
n − 1.
s2 = (x − x)2n − 1
s2 = (x − x)2n − 1
The squared deviations were found previously as shown in the table below.

Since there are nine different brands of Swiss cheese represented in the sample, n = .
n = .
Substitute n and the squared deviations into the formula and simplify to obtain the sample variance.
s2 = (x − x)2n − 1 = 676 + 121 + 225 + 121 + 324 + 961 + 25 + 0 + 9 − 1 =
s2 = (x − x)2n − 1 = 676 + 121 + 225 + 121 + 324 + 961 + 25 + 0 + 9 − 1 =
