In this video titled *"Cumulative Frequency Polygon,"* students of Statistics Class 11 will learn how to construct and interpret cumulative frequency polygons, a valuable graphical tool used in data analysis. The video will guide you step-by-step through the process, starting with the concept of cumulative frequency and its importance in summarizing data sets. You'll see how to calculate cumulative frequencies from a given frequency distribution and how to plot them on a graph to create a cumulative frequency polygon or Ogive.

The video will use clear examples to show the difference between "less than" and "more than" cumulative frequency polygons and explain their applications in comparing data trends and distributions. By the end of this lesson, you'll be able to create cumulative frequency polygons on your own and understand how they can be used to analyze and interpret statistical data effectively. This video is perfect for students preparing for exams or those seeking a deeper understanding of data representation techniques in statistics.
