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 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.
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.

To construct a histogram, first decide how many bars or intervals, also called classes, represent the data. Many histograms consist of five to 15 bars or classes for clarity. The number of bars needs to be chosen. Choose a starting point for the first interval to be less than the smallest data value.
Learn what a frequencypolygon is in maths, how to draw it, and see worked examples for exams. Compare with histograms and master step-by-step graph construction.
To produce a frequencydiagram data is required. The data often comes in the form of a table. To create a frequencydiagram: Look for the largest frequency in the table. Draw a vertical...
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 frequencypolygon is another way to show a frequency distribution on a graph. In addition to being an alternate for the histogram, the frequencypolygon is also an outcome of the histogram.
