Asked by Bridget

a sample consists of the following n =6 scores: 2, 7, 4, 6, 4, and 7 compute the mean and standard deviation for the sample
Answered by PsyDAG
Find the mean first = sum of scores/number of scores

Subtract each of the scores from the mean and square each difference. Find the sum of these squares. Divide that by the number of scores to get variance.

Standard deviation = square root of variance

I'll let you do the calculations.
