A frequency polygon is a type of line graph where a line segment curves to join the midpoints of all the class intervals. The shape of the curved line helps in providing accurate data. Both a line graph and frequency polygon graph are widely used when data is required to be compared.

What is a frequency polygon? A frequency polygon is a graph that shows the frequencies of grouped data. It is a type of frequency diagram that plots the midpoints of the class intervals against the frequencies and then joins up the points with straight lines.
A frequency polygon is used to display grouped data. To draw a frequency polygon we plot the midpoint of the group against the frequency and then join the points with straight lines. Here is a frequency table showing the time, in minutes, it took for 25 students to get to school one day.
25 de abr. de 2024 · A frequency polygon is a type of line graph where the frequencies of classes are plotted against their midpoints. This graphical representation closely resembles a histogram and is typically used for comparing data sets or showing cumulative frequency distributions.
30 de jun. de 2023 · A frequency polygon can be created for the same set of data. Instead of drawing bars, plot the midpoint of the class interval and the frequency. These points are joined by line segments.
23 de abr. de 2022 · Frequency polygons are a graphical device for understanding the shapes of distributions. They serve the same purpose as histograms, but are especially helpful for comparing sets of data. Frequency polygons are also a good choice for displaying cumulative frequency distributions.
