Mean of goals scored by Ronaldo and Messi for each year for the past 5 years is 48 and 50. Standard deviation for each of them is 6 and 4 respectively. Who is more consistent?
Messi
We can say the player with less Coefficient of variation is more consistent in his performance.
C.V(Ronaldo ) = σx×100=648×100=12.5
C.V(Messi ) = σx×100=450×100=8
You can clearly see Ronaldo has more variance compared to Messi. So Messi is more consistent
