Q2 of 40 Page 86

Draw a histogram to represent the following frequency distribution.

The given distribution is in inclusive form. It should be converted in exclusive form


Upper limit of 1st interval is 19


Lower limit of 2nd interval is 20


= = = 0.5


Actual upper limit = Stated upper limit +


Actual lower limit = Stated lower limit –


∴ Frequency distribution table

Take class intervals as (10-20), (20-30), ... and answer the following:


(i) What does the frequency corresponding to the third class interval mean?


(ii) What is the size of each class interval? Find the midpoint of the class interval 30-40.


(iii) What is the range of the given set of scores?
