It also means that (100-15)% or 85% of the scores is greater than the score of 63.

It also means that 70% of the scores is above the score of 8. 1. Q3 = 94 of the scores is less than or equal to 94 of the scores is greater than the score of 94 2. D8 = 17 of the scores is less than or equal to 17 of the scores is greater than the score of 17 3. P90 = 42 of the scores is less than or equal to 42 of the scores is greater than the score of 42 4. D4 = 28 of the scores is less than or equal to 28 of the scores is greater than the score of 28 5. P33 = 94 of the scores is less than or equal to 94 of the scores is greater than the score of 94
