Q. Prepare a frequency distribution table for the scores given:
42, 22, 55, 18, 50, 10, 33, 29, 17, 29, 29, 27, 34, 15, 40, 42, 40, 41, 35, 27,
44, 31, 38, 19, 54, 55, 38, 19, 20, 30, 42, 59, 15, 19, 27, 23, 40, 32, 28, 51.
Take the class intervals as 10-20, 20-30, 30-40, 40-50, 50-60.
From the frequency distribution table answer the following questions:
(i) What does the frequency corresponding to the class interval 20-30 indicate?
(ii) In which class intervals are the scores 10, 20 and 30 included?
(iii) Find the range of the scores.
