9, 17, 12, 20, 9, 18, 25, 17, 19, 9, 12, 9, 12, 18, 17, 19, 20, 25, 9, 12, 17, 19, 19, 20, 9 (2 marks)
(i) What is the highest mark? (1 mark)
(ii) Which mark is occurring more frequently? (1 mark)
Construct a frequency distribution table for the following marks obtained by 25 students in a history test in calss VIII of a school :
9, 17, 12, 20, 9, 18, 25, 17, 19, 9, 12, 9, 12, 18, 17, 19, 20, 25, 9, 12, 17, 19, 19, 20, 9
(i) What is the range of marks ?
(ii) What is the highest mark ?
(iii) Which mark is occurring more frequently ?
Using the data, given below, construct a frequency distribution table: 9, 17, 12, 20, 9, 18, 25, 17, 19, 9, 12, 9, 12, 18, 17, 19, 20, 25, 9 and 12. Now answer the following: (ii) How many numbers are more than 20 ?
Given below are marks obtained by 20 students in Math out of 25.
21,23,19,17,12,15,15,17,17,19,23,23,21,23,25,25,21,19,19,19
Prepare a frequency distribution table for the given data.
