Question 4 The following is the record of goals scored by team A in a football session: For the team B, mean number of goals scored per match was 2 with a standard deviation 1.25 goals. Find which team may be considered more consistent? The group having more Coefficient of Variation will be more variable. Coefficient of Variation (C.V.) = / 100 where = Standard Deviation = Mean Finding standard deviation & mean of team A
