We are given the following marks secured by 25 students in an examination . 23,28,30,32,35,36,36,40,41,43,44,44,45,48,49,52,53,54,56,56,58,61,62,65,68. (i)Arrange this data in the form of a frequency distribution taking the following class intervals. 20-29,30-39,40-49,50-59, and 60-69 (ii) Draw the frequency polygon and ogive for the above data.

The marks scored by 40 students of class VIII in mathematics are given below: 81,55,68,79,85,43,29,68,54,73,47,35,72,64,95,44,50,77,64, 35,79,52,45,54,70,83,62,64,72,92,84,76,63,43,54,38,73,68,52,54. Prepare a frequency distribution with class size of 10 marks.

The marks scored by 40 students of class VIII in mathematics are given below: 81,55,68,79,85,43,29,68,54,73,47,35,72,64,95,44,50,77,64, 35,79,52,45,54,70,83,62,64,72,92,84,76,63,43,54,38,73,68,52,54. Prepare a frequency distribution with class size of 10 marks.

The final makrs in Mathematics of 30 students are as follows {:(53,61,48,60,78,68,55,100,67,90),(75,88,77,37,84,58,60,48,62,56),(44,58,52,64,98,59,70,38,50,60):} What is the range?

How much is the average of the following numbers? 76,48,54,66,70,64

Given below are the marks (out of 100) in mathematics obtained by 20 students of a calss in an annual examination. 23,75,56,42,70,84,92,51,40,63,87,58,35,80,14,63,49,72,66,61. Arrange the above data in ascending order and find (i) The lowest marks obtained. (ii) The highest marks obtained. (iii) The range of the given data.

The marks scored by 40 students of class IX in mathematics are given below: 81, 56, 68, 79, 85, 13, 29, 68, 54, 73, 47, 35, 72, 64, 95, 44, 50, 77, 64, 35, 79, 52, 45, 54, 70, 83, 62, 64, 72, 92, 84, 76, 63, 43, 54, 38, 73, 68, 52, 54. Prepare a frequency distribution with class size of 10 marks.

The final makrs in Mathematics of 30 students are as follows {:(53,61,48,60,78,68,55,100,67,90) (75,88,77,37,84,58,60,48,62,56) (44,58,52,64,98,59,70,38,50,60) How much have scored 75 or more?
