What Is Frequency Polygon. To construct a frequency polygon first examine the data and decide on the number of intervals or class intervals to use on the x-axis and y-axis. The frequency polygon happens to be a special line graph whose use takes place in statistics. One can draw these graphs either separately or combined. There are many ways in which the data can be graphically represented and frequency polygons are the best and the most efficient of all.
The heights of the points represent the frequencies. A frequency polygon is a type of line graph that shows the frequency of a mutually exclusive event occurring. Shown as the black line here. This is widely used in the field of statistics in order to collect and organize the data in a systematic manner. A graph made by joining the middle-top points of the columns of a frequency histogram. A frequency polygon is almost identical to a histogram which is used to compare sets of data or to display a cumulative frequency distribution.
The heights of the points represent the frequencies.
A frequency polygon is a visual representation of a distribution. One can make use of the information that is available in a frequency distribution table for drawings of these graphs. The heights of the points represent the frequencies. For example for frequency distributoion 050302 the frequenc. We can use the frequency polygon to easily compare two or more sets of data. Frequency polygons are one type of graphical representation of data.
