Question

Which one of the following is not the graphical representation of statistical data:

(a) Bar graph

(b) Histogram

(c) Frequency polygon

(d) Cumulative frequency distribution

Answer 1

The correct option is (d)

Cumulative frequency distribution is not the graphical representation of statistical data.

A bar graph also known as a bar chart is a chart that presents data that is grouped into rectangular bars.

A histogram is the visual interpretation of the numerical data using rectangular bars.

A frequency polygon is almost identical to a histogram, which is used to compare sets of data or to display a cumulative frequency distribution.

Cumulative frequency distribution is the total of frequencies that are distributed over different class intervals.
