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.
Learn how to draw frequency polygons using histograms or class marks to represent quantitative data and its frequencies. See a solved example of frequency polygon for heights of students in a batch.
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.
Learn how to make a frequency polygon from a histogram or a frequency table, and how to use it to compare two data sets. A frequency polygon shows the overall distribution of a data set using midpoints and line segments.
2 de abr. de 2023 · Frequency polygons are analogous to line graphs, and just as line graphs make continuous data visually easy to interpret, so too do frequency polygons. 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.
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.
Learn how to create and interpret frequency polygons, a graphical device for understanding the shapes of distributions. See examples of frequency polygons, cumulative frequency polygons, and overlaid frequency polygons.
