Some statistics are derived by adding up the quantitative values of all the members of a class, and then dividing the total by the number of quantitative values in the class.These statistics are called:

A) averages
B) frequencies
C) totals
D) ratios
E) medians

Adding up the quantitative values and dividing by the number of values gives us an average, which is a common type of statistic for summarizing data. Frequencies are counts of how often values occur, totals are just sums of values (without dividing), ratios involve comparing values in different categories, and medians involve finding the middle value of a sorted list of values.
