Question

The lacrosse coach is ordering new uniforms for the team. It would be most useful to know the mean, median, OR mode of the sizes needed?

Answer 1

mode

Answer 2

The mean is good for averages, however it can give answers that are decimal. For example: If there are size 1, 2 and 4 then the MEAN size would be 3.5, which isn't a suitable answer.
The median is ok for averages, however it just gives the middle value as an answer. For example: If there are sizes 1, 2 and 10, the MODE size would be 2. This would be far too small for the player requiring a size 10, so again isn't suitable.
The mode would be the best way to find an average, as it would give the most common size. As an example: If sizes 1,2,3, 4,4 and 5 are needed then size 4 should be ordered as it is the most common of the sizes.
