Describe what is measured by the mean and what is measured by the standard deviation for a set of scores. Describe the set of scores in a sample with a mean of M = 40 and a standard deviation of SD = 4 . (Where are most of the scores located? Where are they centered? What range of values do they cover?)
What will be an ideal response?
The mean identifies the center of the distribution and the standard deviation measures the average distance from the mean. The scores in the specific distribution would be centered around a value of 40 with most of the scores located between 36 and 44 but a few scores as much as 8 or 10 points away from 40.
