Draw a histogram for the frequency distribution of the following data.


Class interval



8-13



13-18



18-23



23-28



28-33



33-38



38-43



Frequency



320



780



160



540



260



100



80


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 = 5 units on X-axis,


1 big division = 50 units 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.
