Question

Write down the step-by-step transformation of a histogram into a frequency Polygon.

Definition Definition Two-dimentional plane figure composed of a finite number of straight line segments connected to form a closed chain or circuit. A polygonal circuit's segments are known as its edges or sides, and the points where two edges meet are known as its vertices or corners.

Expert Solution

Step 1

Frequency polygon:

Frequency polygon is a graph that is used to summarize the grouped data which is continuous for each interval at the midpoint. It is used to depict the shape of the data and to show the trends.

A dot-line-graph is termed as frequency polygon where each dot in the graph is the midpoint for each class interval, and all these dots are connected by a line. The midpoint is the average of the upper and lower boundary of the interval.
