A line plot is a diagram that shows the data on a number line.
8-2: Measures of Central Tendency and Range
measures of central tendency
mean
median
mode
A number used to describe the center of a set of data is a measure of central tendency.
The mode of a set of data is the number that occurs most often. If there are two or more numbers that occur most often, all of them are modes.
