Question

What are the mean, variance, and standard deviation of these values? Round to the nearest 10th.
92, 97, 53, 90, 95, 98

Answer 1

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.
