Introductory Statistics | Constructing a Frequency Polygon | Practice Problem

In this video, I will show how to construct a frequency polygon, a powerful line graph used to visualize the shape of a data distribution. We will walk through the process of identifying class midpoints, plotting those points against their corresponding frequencies, and—most importantly—connecting them to the horizontal axis to "close" the polygon. This visualization is perfect for comparing multiple datasets on the same axes.
