To find the 50th percentile, we need to find the score that is greater than or equal to half of the scores in the distribution. There are a total of 5 scores in this distribution, so the middle score is the third one which has a value of 9. Since 9 is greater than or equal to half of the scores (the first two scores are both 7), the 50th percentile corresponds to a score of 9.0.
