0, 4, 2, 8, 2, 3, 1, 0, 5, 7

7.73333 \dots

Solution steps

Compute the average,

\overset{x}{ˉ} : 3.2

Compute

i = 1 \sum n (x_{i} - \overset{x}{ˉ})^{2} : 69.6

Compute the number of terms in the data set:

n = 10

Compute

Va r (X) = i = 1 \sum n \frac{( x _{i} - x ˉ ) ^{2}}{n - 1} : 7.73333 \dots
