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. To draw frequency polygons, first we need to draw histogram and then follow the below steps:
Frequency polygons are a graphical representation of data distribution that helps in understanding the data through a specific shape. Frequency polygons are very similar to histograms but are helpful and useful while comparing two or more data.
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.
What is a frequency polygon? 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.
Apr 23, 2022 · Frequency polygons are also a good choice for displaying cumulative frequency distributions. To create a frequency polygon, start just as for histograms, by choosing a class interval. Then draw an \(X\)-axis representing the values of the scores in your data.
Feb 6, 2021 · To figure out the number of data points that fall in each class, go through each data value and see which class boundaries it is between. Utilizing tally marks may be helpful in counting the data values. The frequency for a class is the number of data values that fall in the class.
Frequency Polygons. Another type of graph that can be drawn to represent the same set of data as a histogram represents is a frequency polygon. A frequency polygon is a graph constructed by using lines to join the midpoints of each interval, or bin.
