     What is a Frequency Polygon?

     A frequency polygon is a graph used in statistics to visualize data distribution. It resembles a line graph but instead of plotting individual data points, it connects the midpoints of class intervals in a histogram with straight-line segments. This creates a closed loop, unlike a histogram which has bars instead of lines....

     What is Frequency Polygon?

     A frequency polygon is another way to show a frequency distribution on a graph. In addition to being an alternate for the histogram, the frequency polygon is also an outcome of the histogram. While comparing two or more frequency distributions, a frequency polygon is more suitable than using a histogram. Polygons can be constructed for both discrete and continuous series.

   • Frequency Polygon: Definition, Steps to Draw, Examples, Uses

     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. It uses a line graph to represent quantitative data.

     Frequency polygons are one of the great methods to represent statistical data so that it can be read easily. In statistics, we deal with lots of data, and reading it quickly is necessary for solving statistical problems effectively.

     Frequency polygons help us to achieve the same result. In this article, we will learn about frequency polygons, their formula, examples, and others in detail.

   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.

   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. Frequency polygons are used to display data and show the frequency distribution over a continuous scale.

    Nov 28, 2020 · A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin. The heights of the points represent the frequencies. A frequency polygon can be created from the histogram or by calculating the midpoints of the bins from the frequency distribution table.
