Definition Of Frequency Polygon In Statistics. With the help of frequency polygon the data can be interpreted easily. In addition the graph may be used to show the cumulative frequency distribution. A frequency histogram is a bar graph that uses vertical columns to visually show frequencies which is how many times a score occurs. Frequency polygons are a graphical device for understanding the shapes of distributions.
Definition of frequency polygon. If the middle top points of the bars of the histogram are joined a frequency polygon is formed. The number of individuals in a class absolute frequency b. In addition the graph may be used to show the cumulative frequency distribution. The ratio of this number to the total number of individuals under survey relative frequency 5. Figure 23 presents the frequency polygon of the data of Table 21.
A frequency polygon is a visual representation of a distribution.
In addition histograms tend to be rectangles while a frequency polygon resembles a line graph. There are many ways in which the data can be graphically represented and frequency polygons are the best and the most efficient of all. Frequency Polygon - Frequency polygons are one type of graphical representation of data. One can make use of the information that is available in a frequency distribution table for drawings of these graphs. It uses a line graph to represent quantitative data. After choosing the appropriate ranges begin plotting the data points.
