The scores (out of 100) obtained by 33 students in a Mathematics test are :
69,48,84,58,84,48,73,83,48,66,58,66,64,71,64,66,69, 66,83,66,69,71,81,71,73,69,66,66,64,58,64,69and 69.
Prepare a frequency table for the above scores.

Pulse rate (per miute) of 30 persons were recorded as 61,76,72,73,71,66,78,73,68,81,78,63,72,75,80,68,75,62,71,81,73,60,79,72,73,74,71,64,76 and71. Construct a frequency table using class-invervals of equal width,one class interval being (60-65).

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

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),(44,58,52,98,59,70,38,50,60):} What is the lowest score?

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?

The scores of Mathemtics test 75,69,88,95,88,64,75,95,90,88,44,59,88,67,99 find the median and mode of the 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?

The final marks 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) (44,58,52,98,59,70,38,50,60) How many have scored less than 50?

The number of runs scored by a cricket player in 25 innings are as follows: 26,35,94,48,82,105,53,0,39,42,71,0,64,15,34,67,0,42,124,84,48,139,64,47 How many times did the player not score a run?
