How to draw frequency polygons?
Understand the Problem
The question is asking for instructions or guidelines on how to create frequency polygons, which are graphical representations of the distribution of a dataset. To answer this, we will typically explain the necessary steps, including collecting data, organizing it, and plotting the points on a graph based on frequencies.
Answer
Plot points and connect them with lines.
The final answer is a frequency polygon constructed by plotting points of class marks and their corresponding frequencies, then connecting these points with straight lines.
Answer for screen readers

More Information
A frequency polygon is useful in comparing different sets of data and visualizing frequency distributions in a simpler way compared to histograms.
Tips
Avoid connecting the points freehand or as a curve; ensure they are linked with straight line segments for accuracy.
