What is the variance rounded to the nearest tenth?
Enter

Given:

The scores that Jenna has received on her seven quizzes is 16, 13, 20, 16, 12, 17, 18.

We need to determine the variance.

Mean:

The mean of the data is given by

Thus, the mean of the given data is 16.

Variance:

The variance of the data can be determined using the formula,

where is the mean and n is the number of terms in the distribution.

Thus, we have;

Simplifying the terms, we get;

Rounding off to the nearest tenth, we get;

Thus, the variance is 6.6

The variance is 6.6
