A statistical question is one where there is
variability in the answers to the question.

Numeric data from a statistical question can be displayed in a line plot.
A line plot is a data display, along a number line, which shows frequency.
The frequency is represented with a marker, like an x or a dot.

Mean, median, and range can be used to analyze data in a line plot.

The mean, or average, of a data set is the sum of the values in the data set divided by the number of values in the data set.
The median is the middle value in an ordered data set.
The range is the difference between the greatest and least values in a data set.
