Textbook Problem

Calculate the variance for the following population of N = 5 scores: 4, 0, 7, 1, 3.

To determine

To Find: The variance for the population scores.

Explanation

Given info:

The set of scores is 4, 0, 7, 1, and 3.

Calculation:

The formula of mean is,

μ=xiN

The formula of Sum of squared deviations is,

SS=(xiμ)2

The formula of variance is,

s2=SSN

The mean of scores is,

μ=xiN=4+0+7+1+35=155=3

The sum of squared deviations (SS) of scores is,

SS=(xiμ)2<
