Question

The manager of a hair salon is analyzing the number of customers who visit the salon each day. If she wants one number to summarize all the values of the data set, what type of measure should she use?

A. a measure of center, such as the median
B. a measure of variation, such as the mean absolute deviation
C. a measure of variation, such as the mode
D. a measure of center, such as the interquartile range

Answer 1

the answer would be A. a measure of center, such as the median

Explanation:

A measure of center for a numerical data set summarizes all of its values with a single number, while a measure of variation describes how its values vary with a single number.

Some examples of a measure of center are median and mode. Some examples of a measure of variation are interquartile range and mean absolute deviation.

The salon manager wants one number to summarize all the values of the data set.
