If someone’s score was in the 16th percentile, what score would the individual have?
Answer:Correct! According to the 68-95-99.5 Rule, 68% of the scores fall within one standard deviation of the mean (one standard deviation above and one standard deviation below). This leaves 16% of the scores to fall below and 16% of the scores to fall above the scores that are within one standard deviation of the mean. If a student is in the 16th percentile, that means he/she has scored at one standard deviation below the mean. The mean is 517 and the standard deviation is 117. 514 − 117 = 397.
