A student scored 70 percent on a test, and was in the 80th percentile. Explain these two numbers.
The 70% score shows that the student answered 70% of the questions correctly. If there were 100 questions, he answered 70 of the questions correctly.
At the 80th percentile, 80% of the other students scored below 70% and 20% scored above 70%.
