Scatterplots are often used in mathematics to portray collected points that have value. It comparing two different categories at one time, for example above it compares weight of a person which is on the x axis to their height on the y axis. The way you plot the information on the graph is by first going across the bottom to find where your first value (weight) falls then go up to find where the second value height in this case. Scatterplots are great to use when you are trying to determine where the outliers are because they are easy to locate rather then going through a set of data.
