Prepare the frequency distribution table for the given set of scores:
39, 16, 30, 37, 53, 15, 16, 60, 58, 26, 28, 19, 20, 12, 14, 24, 59,
21, 57, 38, 25, 36, 34, 15, 25, 41, 52, 45, 60, 63, 18, 26, 43, 36, 18,
27, 59, 63, 46, 48, 25, 33, 46, 27, 46, 42, 48, 35, 64, 24.
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?
