Question

In a class of 30 students, Bruce is ranked 29th, what is his percentile rank? In that same class Jennifer is ranked 3rd, what is her percentile rank?

Answer 1

The percentile is just the percent of students LOWER than the given student.

For Bruce, since he is ranked 29th, there is only 1 student lower. 1/30 = 3.33%. Bruce has a percentile rank of 3.33 because 3.33% of the class is below him.

For Jennifer, she is ranked 3rd, so there are 27 students lower than her. 27/30 = 90%. Jennifer has a percentile rank of 90 because 90% of the class is below her.
