Question

Draw a frequency polygon using histogram from the following data.

Class: 10-20, 20-30, 30-40, 40-50, 50-60, 60-70
Frequency: 4, 8, 12, 10, 4, 15

Answer 1

To draw a frequency polygon using a histogram, create a frequency distribution table, plot the points on a graph, and connect the points with line segments.

Step-by-step explanation:

To draw a frequency polygon using a histogram from the given data, we first need to create a frequency distribution table. Let's start by listing the class intervals and their corresponding frequencies:

ClassFrequency10-20420-30830-401240-501050-60460-7015

Next, we can plot the points on a graph, with the class intervals on the x-axis and the frequencies on the y-axis. The plotted points will form the vertices of a frequency polygon. Finally, we connect the points with line segments to create the frequency polygon.
