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.
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
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.
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.
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.
frequency polygon: A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. absolute frequency polygon: An absolute frequency polygon has ‘peaks’ that represent the actual number of points in the associated interval. relative frequency
Frequency Polygon: Definition and How to Make One. Statistics Definitions. A frequency polygon is very similar to a histogram. In fact, they are almost identical except that frequency polygons can be used to compare sets of data or to display a cumulative frequency distribution.
Jan 16, 2021 · 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. After choosing the appropriate ranges, begin plotting the data points. After all the points are plotted, draw line segments to connect them.
