Frequency polygons
A frequency polygon is a graphical representation that displays the distribution of data in a given range of values. It consists of bars or segments of equal width, where each bar represents the frequency of occurrences of a specific value in the data set. The width of the bars is determined by the relative frequency of the values in the data.
Cumulative frequency
Cumulative frequency is a statistical measure that provides valuable insights into the data. It shows the total frequency of observations that have occurred up to a certain point in the data. The cumulative frequency can be calculated by adding the frequency of all values up to that point to the frequency of the value at that point.
The relationship between frequency polygons and cumulative frequency is as follows:
A frequency polygon represents the distribution of data in a range of values, with each bar representing the frequency of occurrences of a specific value.
The cumulative frequency is the total frequency of observations that have occurred up to a certain point in the data, and it is calculated by adding the frequency of all values up to that point to the frequency of the value at that point.
Frequency polygons and cumulative frequency are powerful tools for analyzing and understanding data distributions. They can be used to identify patterns and trends in the data, and to make predictions about future data values
