Question

The marks obtained by 10 students in Mathematics are given below: 40,20, 13, 49,50,10,29,37,0,5 i. Find the mean marks ii. i Find the range​

Answer 1

Answer:

Ascending Order = 0,5,10,13,20,29,37,40,49,50

i. Mean of Marks = (Sum of all marks obtained by the group of students)/  (Total number of marks)

=  0+5+10+13+20+29+37+40+49+50/ 10

= 253/10

= 25.3

ii.  Range = Highest marks – Lowest marks

= 50-0

= 50
