In the set of scores 92, 85, 92, 78, 85, which statement correctly describes the mean and the mode?

Explanation:
Mean and mode describe different ideas about a data set. The mean is the arithmetic average: add all the numbers and divide by how many numbers there are. Here, 92 + 85 + 92 + 78 + 85 = 432, and there are 5 scores, so the mean is 432 ÷ 5 = 86.4. The mode is the value that appears most often. In this set, 92 appears twice and 85 also appears twice, while 78 appears once. Since two values tie for most frequent, the data are bimodal, with modes 85 and 92. So the description should say the mean is 86.4 and the mode is 85 and 92 (bimodal).
