    Recognize and use measures of center and measures of variation to describe data. Recognize that 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.

    Step-by-step explanation:

    The measure of center of a group of data is a single central value such as the mean and the median.

    The mean is the arithmetical average of the sum of the data and the median is the middle value of the data when placed in ascending sequence.

    The measure of variability gives an indication of the spread of the data about the mean. Examples are the Standard Deviation and the Interquartile Range.
