What is the mean of the heights for the dataset: 74, 82, 78, 72, 78, 73, 78, 72, 78, 81?

Explanation:
Mean height is the average value, found by summing all the heights and dividing by how many measurements there are. Add them up: 74 + 82 + 78 + 72 + 78 + 73 + 78 + 72 + 78 + 81 equals 766. There are 10 measurements, so 766 ÷ 10 gives 76.6. The mean height is 76.6 inches (about 6 feet 4.6 inches).
