The marks scored by Il students in Mathematics test are as follows:
34, 37, 30, 38, 50, 34, 34, 38, 36, 45, 31
Find the value of (a) range (b) arithmetic mean (c) median​

Answer 1

Step-by-step explanation:

(a) range= largest value - smallest value

= 50 - 30

= 20

(b) mean = sum of all observation/total number of observation.

mean= 34+37+30+38+50+34+34+38+36+45+31/11

= 407/11

= 37

(c) median (for odd value)= (n+1/2)th

= 11+1/2

= 12/1

= 6 th

value arranged in assending order.

30,31,34,34,34,36,37,38,38,45,50

median is 36.
