Jesse ranked 37th in a graduating class of 180 students, so 143 students ranked below him. At what percentile does his rank put him?

1. The number of students ranked below Jesse is 180 minus 37, which is 143 students. 2. Exactly one student holds the rank of 37, so the tie count y is 1. 3. The numerator is 143 plus half of 1, which is 143.5. 4. Dividing 143.5 by 180 and multiplying by 100 gives 79.72. 5. Rounding places Jesse at the 80th percentile of his class. 6. Answering with 37 reports his rank rather than his percentile, and 20 reports the share of students above him. _Source: OpenStax Introductory Business Statistics (CC BY 4.0), Ch 2 "Descriptive Statistics", section 2.2 Measures of the Location of the Data_
