-When finding percentiles, if the locator L is not a whole number, one procedure is to interpolate so that a locator of 23.75, for example, leads to a value that is 3/4 of the way between the 23rd and 24th scores. Use this method

Quizplus · Accepted Answer

To find P75, calculate L = 0.75 * 11 = 8.25. Interpolate between the 8th (83) and 9th (94) scores: 83 + 0.25 * (94 - 83) = 85.75.
