We start by looking at an age distribution histogram for a local area, then introduce the concept of a frequency polygon—explaining why it’s called that and how it can be more useful than a histogram. You’ll learn: • Why use a frequency polygon? Discover its benefits in showing trends, enhancing aesthetics, and comparing multiple data sets. • Step-by-step plotting: Find class marks, plot the points, and extend the graph to the x-axis to complete the polygon. • Practical applications: See real-life examples of how frequency polygons can simplify data interpretation.
