What is frequency polygon What are its uses?
Correspondingly, what is frequency polygon with example?
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.
Also Know, what are the characteristics of frequency polygon? 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. In addition, histograms tend to be rectangles while a frequency polygon resembles a line graph.
Accordingly, what is frequency polygon?
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.
How do you construct a frequency table?
To construct a frequency table, we proceed as follows:
- Construct a table with three columns. The first column shows what is being arranged in ascending order (i.e. the marks).
- Go through the list of marks.
- Count the number of tally marks for each mark and write it in third column.
