   • Frequency Polygon: Definition, Steps to Draw, Examples, and FAQs

     Frequency polygon is a statistical tool equivalent to a Histogram that is used to represent and compare data when they are given in the form of cumulative frequency. A frequency polygon uses a line graph to represent quantitative data. Frequency polygons are one of the great methods to represent statistical data so that it can be read easily. In statistics, we deal with lots of data, and reading it quickly is necessary for solving statistical problems effectively.

     Frequency polygons help us to achieve the same result. In this article, we will learn about, frequency polygons, their formula, examples, and others in detail.

     Frequency Polygon in Statistics

     A visual representation of the frequency distribution of continuous data is the frequency polygon. Karl Pearson, an English statistician, made the initial presentation of it in the late 19th century. Based on the research of earlier statisticians like Francis Galton and Adolphe Quetelet, he put forth the idea. Its value comes from its capacity to graphically portray data, making understanding and analysis easier. They, therefore, serve as an important tool in statistics, assisting researchers in finding patterns and trends in huge...

     What is Frequency Polygon?

     A frequency polygon is another way to show a frequency distribution on a graph. In addition to being an alternate for the histogram, the frequency polygon is also an outcome of the histogram. While comparing two or more frequency distributions, a frequency polygon is more suitable than using a histogram. Polygons can be constructed for both discrete and continuous series.

     (I) Steps to Draw Frequency Polygon in Discrete Series

     The steps required to construct a frequency polygon in the case of discrete series are: 

     Draw a straight line...

     • Write the values of the given variable (say, X) on the X-axis and the corresponding frequencies on the Y-axis.
     • Draw a straight line connecting the points of the various frequencies.

     Without sample data it is hard to answer but try to add color=factor(time) (where time is name of your column with time periods). This will draw lines for each time period in different color.

     qplot(latitude, data = lat_data, geom = "freqpoly", binwidth = 0.25, color=factor(time))-
