Question

Question 2: A student in an 887 class is informed that his score is in the 75th percentile of this test. This means that 221 students scored higher than his in this test. True or false

Answer 1

Given that,  A student in an 887 class is informed that his score is in the 75th percentile of this test. This means that 221 students scored higher than his in this test.

Here, 221/887 = 0.2491 ( approx 25%)

that means 25% students scored higher than his in this test.

Therefore, above statement is True

Note: Example for understanding percentiles,

100 people appear for an exam and one is told that his percentile is 80 or that one is placed in 80th percentiles, it means to say that the candidate has done better than other 79% or 80% candidates but still 19% or may be 20% other persons have scored better than he/ she did.
