The statistics of runs scored in a series by four batsmen are provided in the following table. Who is the most consistent batsman of these four?
Batsman Average Standard Deviation K 31.2 5.21 L 46.0 6.35 M 54.4 6.22 N 17.9 5.90

- K
- M

- N
- K
Correct Option: B
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) = | ||
| 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.
