Numerical Ability Easy Questions and Answers

Most consistent player is the one with least dispersion in the scores. For this, Coefficient of Variance is used to measure relative measure of dispersion between two sets.

Coefficient of Variance(CV) =	Standard Deviation
	Mean

Calculating it for all the four players.
K's CV = 0.167
L's CV = 0.138
M's CV = 0.114
N's CV = 0.329
Larger the value of CV, less consistent is the player. So the most consistent player is M.

Correct Option: B

P(A) = 1 – P (A)

P(A) = 1 -	13	=	77
	90		90

Correct Option: D

P(A) = 1 – P (A)

P(A) = 1 -	13	=	77
	90		90
