Calculating Mean Height from a Data Set

In a recent study, the heights (in inches) of a group of students were recorded as follows:

62, 65, 70, 68, 64, 72, 65, 69, 67, 71, 73, 66, 64, 68, 70

To analyze the data set, we will compute both the mean and the median heights of the students.

Determine the mean height of the given data set.
