The significant benefit of a cumulative frequency polygon above a histogram and frequency polygon is that it can demonstrate the total number of observations that are less than the upper limit of a specific class.
What is cumulative frequency polygon?
A line segment-joined plot of a cumulative frequency against by the upper class boundary. An ogive would be any continuous cumulative frequency curve, along with a cumulative frequency polygon.
Some main points related to cumulative frequency polygon are-
- The cumulative frequency graph can graphically represent data organized in the pattern of a cumulative frequency distribution.
- The method for drawing cumulative frequency polygons as well as cumulative frequency curves and perhaps ogives is similar.
- The only distinction in that a cumulative frequency polygon is formed by connecting points with line segments, whereas the cumulative frequency polygon is formed by connecting points with a free hand smooth curve.
- The cumulative frequency polygon is primarily a line graph drawn on graph paper by projecting the actual lower and upper limits of a class intervals on the x-axis and their respective cumulative frequencies on the y-axis.
