Chapter 2| Descriptive Statistics 83

Frequency polygons are useful for comparing distributions. This is achieved by overlaying the frequency polygons drawn for different data sets.

Short Answer

Expert verified

At inauguration, the frequency polygon of the specified age

When we look at the graph, we can see that the maximum frequency is at55.

Step by step solution

01

Given

Here we have

02

Explanation

The frequency polygon determines what the frequency will be against each observed X.
It indicates which X frequency is the lowest and which X frequency is the highest.
As a result, we can quickly determine the highest and lowest occurrences of X.
In the graph, we have displayed the greatest frequency for 55thage for each district.
