Answer to Question 1

ANS: A
The mode and median are not affected by outliers as is the mean.

Answer to Question 2

ANS: C
The standard deviation indicates the average deviation of a score from the mean in that particular sample.
The frequency tells how many times a score occurs in the distribution, not where it falls. The standard deviation indicates the average deviation of a score from the mean in that particular sample.
The mean is simply the average of the scores and would not indicate a relationship to the distribution of scores. The standard deviation indicates the average deviation of a score from the mean in that particular sample.
Variance is a calculated value and has no absolute value. The standard deviation indicates the average deviation of a score from the mean in that particular sample.
