Sagot :
Angie ranks 10th in a class of 40 her percentile rank is?
PR = percentile rank M = number of rank at x Y = total number of ranks then, M = 10 Y = 40 PR = 10/40 x 100 = .25 x 100 = 25 Therefore, Angie's percentile rank is 25%. Other Example: There are 20 students in a class. Both Alan and Ellen are ranking 10th among the students 20.
