Question

5 of 10 concepts completedmultiple choice questionwhich of the following is an advantage of a cumulative frequency polygon over a histogram or frequency polygon?it can show the total number of observations less than a particular class upper limit.it shows class midpoints as points on points on a polygon.it can show the number of observations in a given class.

Explanation:

A histogram and regular frequency polygon display the count of observations in individual classes, and a regular frequency polygon uses class midpoints. A cumulative frequency polygon is specifically designed to show the running total of observations, meaning it can directly illustrate how many observations are less than the upper limit of a specific class, which the other two cannot do as their primary function.

Answer:

It can show the total number of observations less than a particular class' upper limit.
