Question

If you wanted to compare the shoe sizes and the heights of all the students in your math class, what graph would you use?

Answer 1

You would use a scatterplot.

Explanation:

Set out the `x`-axis to represent the height and the `y`-axis to represent the shoe size (or the other way around).
Put a dot for every size/height combination, and you might get an idea of the correlation between the two variables.
You may do a correlation test later.
