4. Dot Plots A dot plot shows each item of numerical data above a number line. Dot plots make it easy to see gaps and clusters in a data set, as well as the spread across the axis. To make a dot plot with a data set: 1. Identify the minimum and the maximum values in the data. 2. Label the number line beginning with the minimum value. Label equal intervals until you reach the maximum value. 3. For each value in the data set, put a dot above that value on the number line. If a value occurs more than once, stack the dots.
