A frequency polygon is a many sided
polygon that represents the distribution of a set of data values. It is created by connecting the midpoints of the tops of the bars in a histogram. The horizontal axis represents the data values and the vertical axis represents the frequency or count of each data value. The points on the graph are then connected with line segments to create a polygon shape.
The frequency polygon is used to visualize the shape and distribution of the data. It can help identify patterns, trends, and outliers in the data set. Additionally, it allows for easy comparison between different data sets.
