For those who are new to this term, a frequency polygon is a visual representation of data using a line graph to draw the frequency values based on their classes. It allows you to understand the distribution as well as the shape of the data through the line chart, which is closed on both ends to give it a polygon shape. Follow the steps below to cr...
Let’s start with some data, such as the science test score data shown below. The Lower Limit and Upper Limit data columns are the class bounds, representing the starting and ending points, respectively. (For example, the first class includes any scores between 10, the lower limit, and 29, the upper limit.) Frequency measures the number of students ...
Below you’ll find some commonly asked questions regarding frequency polygons. Read on for more information.
Frequency Polygons. A frequency polygon is used to display grouped data. To draw a frequency polygon we plot the midpoint of the group against the frequency and then join the points with straight lines. Here is a frequency table showing the time, in minutes, it took for 25 students to get to school one day. Time.
Apr 25, 2024 · Last Updated : 25 Apr, 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.
Apr 23, 2022 · 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. Mark the middle of each class interval with a tick mark, and label it with the middle value represented by the class.
