STANDARD DEVIATION

standard deviation is a measure of the dispersion of a statistical sample, equal to the  square root of the variance.  To compute the standard deviation, compute first the mean score

Solution :

Step 1. compute the  Mean score

Mean = (∑▒x)/n

Mean = (7+ 7+8+12+ 14+ 14+ 14+ 14+ 15+ 15)/10

Mean = 12
