Textbook Problem

For the following set of scores: 1, 5, 7, 3, 4

  • a. Assume that this is a population of N = 5 scores and compute SS and variance for the population.
  • b. Assume that this is a sample of n = 5 scores and compute SS and variance for the sample.

(a)

To determine

The SS and variance for the population scores.

Explanation

Given info:

The population scores are 1, 5, 7, 3 and 4.

Calculation:

The formula of population mean is,

μ=xiN

The formula of sum of squared deviations is,

SS=(xiμ)2

The formula of variance is,

σ2=SSN

The mean of scores is,

μ=xiN=1+5+7+3+45=205=4

The sum

(b)

To determine

The SS and variance for the sample scores.
