Percentile vs. Percentage
A position in a ranked distribution versus a fraction out of 100.
The comparisoni
“She scored in the 90th percentile — meaning 90% of test-takers scored lower. PERCENTAGE is the fraction (90% means 9 out of 10).”
The ruleii
¶
PERCENTILE = ranking. PERCENTAGE = fraction.
PERCENTAGE is a fraction (90% = 9/10). PERCENTILE is a ranking position — the 90th percentile is the score below which 90% of scores fall. Two different concepts; the words sound similar.
Memory aidiii
Remember it like this
Percentile ranks. Percentage shares.
