Max is analyzing the test scores he earned in his biology class. The class had 7 tests, on which he scored 85, 93, 78, 90, 88, 97, and 88. | What is the mean of the data set? | What is the median of the data set? | What is the mode of the data set?

The scores add to 619, so the mean is 619 ÷ 7 = 88.43, matching choice C, 88.43. In order, the scores are 78, 85, 88, 88, 90, 93, and 97, so the middle score—and the median—is 88. The score 88 appears most often, so the mode is also 88; neither the median nor the mode is listed among the choices.
