Answers
Step-by-step explanation:
Given below is the frequency distribution of the heights of 50 students of a class:
Class interval: 140−145 145−150 150−155 155−160 160−165
Frequency: 8 12 18 10 5
Draw a histogram representing the above data.
ANSWER:
The class limits are represented along the x-axis on a suitable scale and the frequencies are represented along the y-axis on a suitable scale. Taking class intervals as bases and the corresponding frequencies as heights, the rectangles can be constructed to obtain the histogram of the given frequency distribution as shown in the figure below:

Question 2:
Draw a histogram of the following data:
Class interval: 10−15 15−20 20−25 25−30 30−35 34−40
Frequency: 30 98 80 58 29 50
ANSWER:
The class limits are represented along the x-axis and the frequencies are represented along the y-axis on a suitable scale. Taking class intervals as bases and the corresponding frequencies as heights, the rectangles can be drawn to obtain the histogram of the given frequency distribution. The histogram is shown below:
