A sample of n = 6 scores has SS = 30 and s² = 6.If the 6 scores were a population,the value of SS would still be 30,but the variance would be σ² = 5.

For a sample, variance (s²) is calculated by dividing the sum of squared deviations (SS) by the degrees of freedom (n-1), which in this case is 5 (6-1), giving a variance of 6. For a population, variance (σ²) is calculated by dividing SS by the number of scores (n), which gives a variance of 5 (30/6).
