Mean is best measure of average.
Given:
Class rank is at least = 90th percentile
Rank 30 out of 128 student
Find:
1. Invited for membership or not
2. Best measure of average
Computation:
Rank in total = [(100 - Percentile)(Total students)]/100
30 = [(100 - Percentile)(128)]/100
3000 = [(100 - Percentile)(128)]
23.4375 = 100 - Percentile
Percentile = 100 - 23.4375
Percentile = 76.5625
Since Percentile smaller than 90, So, you will not invited to membership
Mean is best measure of average.
