A large retail company gives an employment screening test to all prospective employees. Franklin Gilman recently took the test and it was reported back to him that his score placed him at the 80th percentile. Therefore:
1. Franklin scored as high or higher than 80 percent of the people who took the test.
2. Franklin was in the bottom 20 percent of those that have taken the test.
3. 80 people who took the test scored below Franklin.
4. Franklin's score has a z-score of 80.

Explanation:

The percentile is use for comparisons. If a value is said to be XX percentil, then, XX percent of the people scored that value or less than it.

For the given case, the score of Franklin Gilman in the test placed him at the 80th percentile, then it means that only 20% had a greater score and he scored as high or higher than 80 percent of the people who took the test.
