To show the relationship between two data sets using ordered pairs plotted in a coordinate plane
Relationship of two data sets, coordinate plane
Now, we want to choose an appropriate data display for showing a mode of a data set. Recall that a mode is the most common value in a data set. Therefore, we should use a dot plot because it shows how many times each value occurs. Let's take a look at the example dot plot.
Here, the mode, or the most common value, is 3 because we have the greatest number of dots above this value.
