Question

1,5,2,1,3,6
Assuming that these weights constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places. How do I break down this to find my answer

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.
