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
In a particular hospital, 6 newborn babies were delivered yesterday. Here are their weights (in ounces):
112, 96, 109, 126, 99, 106
Assuming that these weights constitute an entire population, find the standard deviation of the population. Round your answer to at least two decimal places.
Mean=648/6= 108
I can find the mean but can’t remember what I do next.
