Frequency polygons are a type of line graph that helps in providing accurate data through a curved shaped line. Learn more about this interesting concept of frequency polygons, steps to plot, and solve a few examples.
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.

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.
Los polígonos de frecuencia también son una buena opción para mostrar distribuciones de frecuencia acumulativas. Para crear un polígono de frecuencia, comience igual que para los histogramas, eligiendo un intervalo de clase. Luego dibuja unX X -axis representing the values of the scores in your data.
