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|| |
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.
