Frequency Polygon In Statistics. A histogram is a series of rectangular bars with no space between them and is used to represent frequency distributions. Statistics - Bar graph Histogram Frequency polygon. They serve the same purpose as histograms but are especially helpful for comparing sets of data. A frequency polygon is a visual representation of a distribution.
Frequency polygons are analogous to line graphs and just as line graphs make continuous data visually easy to interpret so too do frequency polygons. In this tutorial you will learn how to draw few very important and basic graphs in statistics. It is similar to a histogram which is also used to visualize grouped data. This is widely used in the field of statistics in order to collect and organize the data in a systematic manner. Seeing the data in this format helps us visualize and. We can create a frequency polygon from a histogram also.
They serve the same purpose as histograms but are especially helpful for comparing sets of data.
What is frequency polygon in statistics. First you need to have the frequency distribution of the data either in terms of the frequency of individual values or in terms of classes. With the help of frequency polygon the data can be interpreted easily. It is used to depict the shape of the data and to depict trends. That is for every constant c there are just as many data points that are c less than x 0 as there are that are c greater than x 0. In this tutorial you will learn how to draw few very important and basic graphs in statistics.
