A frequency polygon in statistics is a graph that displays the distribution of a set of continuous data. It aims to visually represent a group of consistent data issuance, making it easier to interpret and analyse by plotting the frequency of each interval on the vertical axis and the midpoint of each interval on the horizontal axis. Frequency polygons can be defined as a graphical representation of data distribution which helps in understanding the data via the help of a specific shape. Frequency polygons are very similar to histograms and help when comparing two or more data. The graph helps to show cumulative frequency distribution data by means of a line graph. Learn the steps to draw a frequency polygon , a line graph that represents quantitative data and its frequencies. See an example of how to construct a frequency polygon from a table of heights of students. However, unlike the histogram, the frequency polygon can be easily utilized to compare multiple distributions on the same graph. In some cases, a histogram and a frequency polygon can be used simultaneously to get a more accurate picture of the distribution shape. How to Create a Frequency Polygon in Excel
