Q:

A test has a mean of 80 and standard deviation of 4. what score would be 1 deviation from the mean

Accepted Solution

A:
Any score between 76 and 84 will be 1 deviation from the mean.

To figure this out you subtract 4 from 80 (80-4 = 76) and you add 4 to 80 (80+4) = 84 and that tells you that most of the scores will fall between 76 and 84 which is 1 deviation from the mean.Β
