variance of 2,3,4,5,6,0.2,0.1,0.2,0.2,0.3

variance

5.12444 \dots

Solution steps

Compute the average,

\overset{x}{ˉ} : 2.1

Compute

i = 1 \sum n (x_{i} - \overset{x}{ˉ})^{2} : 46.12

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} : 5.12444 \dots

5.12444 \dots
