Frequency polygons are a visually substantial method of representing quantitative data and its frequencies. Let us discuss how to represent a frequency polygon. Steps to Draw Frequency Polygon
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.
Apr 25, 2024 · Frequency Polygons in Statistics: 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.
Frequency polygons are used to display data and show the frequency distribution over a continuous scale. To construct a frequency polygon we need to know the value for the frequency of each group. For example, Below is an example of a frequency polygon, with the associated data table.
What is a frequency polygon? A frequency polygon shows the overall distribution of a data set. It looks a little bit like a line graph–but the points on the graph can be plotted using data from a histogram or a frequency table . Frequency polygons are especially useful for comparing two data sets.
Frequency polygons give an idea about the shape of the data and the trends that a particular data set follows. Let us learn the step by step process of drawing a frequency polygon, with or without a histogram.
Apr 23, 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.
