You scored in the 55th percentile on the GRE. If 2,000 people took the GRE, how many people had a score at least as high as your score?

Answer: 900 people.

Explanation:

If you are in the 55th percentile then that means that you scored better than or at least as good as 55% of people who took the GRE because a peecentile is a measure that states the position of a number in a data set as a percentage.

If calculating how many people had a mark at least as high as your own, that means those people who scored higher than or at least what you scored.

If you scored higher than 55% then that means that,

= 100 - 55

= 45%

45% scored at least as high as you.

2,000 took the test so 45% will be

= 2,000 * 45%

= 900 people.

900 people scored at least as high as you.
