1. Calculate SS, variance, and standard deviation for the following sample of n = 5 scores: 2, 9, 5, 5, 9.

2. A population has a mean of m 5 50 and a standard deviation of s 5 10.

a. If 3 points were added to every score in the population, what would be the new values for the mean and standard deviation?

b. If every score in the population were multiplied by 2, then what would be the new values for the mean and standard deviation?
