Find
a. Mean
b. Median
c. Mode

A

`{:(a" "b" "c),(65" "66" "52):}`

B

`{:(a" "b" "c),(60" "66" "50):}`

C

`{:(a" "b" "c),(65" "72" "52):}`

D

`{:(a" "b" "c),(60" "68" "45):}`

Text Solution

Verified by Experts

The correct Answer is:
A
`55+40+38+45+52+80+85+72`
a. Mean `=(+90+88+76+71+65+52+66)/15`
`=975/15=65`
b. The ascending order of the given scores are:
38,40,45,52,52,55,65,66,71,72,76,80,85,88,90
Meadian `=((15+1)/2)^(th)` observation
=8th observation =66
(c) Mode=Observation having highest frequency
=52
