The heights of 75 students in a school are given below:


Height (in cm)



130-136



136-142



142-148



148-154



154-160



160-166



Number of students

Draw a histogram to represent the above data.

The given frequency distribution is in exclusive form, we will represent the class intervals along the X-axis and the corresponding frequency on the Y axis.


Now take the scale of,


1 big division = 6cm on X-axis,


1 big division = 2 students on Y axis


We will draw the rectangles with the class intervals as basis and the corresponding frequency as the height.


Thus, we get the following histogram.
