Question

Let's say you take an exam worth 240 points and your score marked the 78th percentile of all the exam scores. Based on this you can conclude that ______% of exam takers had scores equal to or better than yours.

Answer 1

Answer:

28%

Step-by-step explanation:

78th percentile means 78% scored less than/equal to you.

100 - 78 = 22%

Answer 2

Here, we are required to determine what percentage of exam takers had scores equal to or better than mine.

The correct answer is therefore, 22%

First, a percentile is a statistical term used to represent each of the 100 equal groups into which a population can be divided according to the distribution of values of a particular variable, (in this case the scores).

Therefore, according to the definition above, Since my score marked the 78th percentile, we can conclude that only (100 - 78)% of the exam takers had scores equal to or better than mine.

The correct answer is therefore, 22%
