Turtle is an inbuilt module of python. <> Frequency Polygon can be constructed in two ways: (i) Using histogram (ii) Without using histogram. A frequency polygon is sometimes used to represent the same information as in a histogram.A frequency polygon is drawn by using line segments to connect the middle of the top of each bar in the histogram.This means that the frequency polygon connects the coordinates at the centre of each interval and the count in each interval. Cumulative Frequency Polygon: Cumulative frequency polygon is similar to a frequency polygon. It is customary to bring the ends of the polygon down to base level by assuming a lower class of a frequency and highest class of a frequency. A frequency polygon is a type of chart that helps us visualize a distribution of values.
