Hi friends, In this session we shall learn all about frequency polygons. A frequency polygon is a 1 dimensional representation of statistical data. A frequency polygon can be drawn for a continuous grouped data with the help of a histogram or it can be done so also without a histogram. Both the methods are covered in the session. We shall also learn how to read data from a given frequency polygon. If you have any doubts or suggestions regarding the session please do write them in the comments section.
