Identify the data set given: 2, 4, 6, 8.
Recall that the mean (average) of a data set is calculated by summing all the values and then dividing by the number of values.
Calculate the sum of the data points: \(2 + 4 + 6 + 8\).
Count the number of data points, which is 4 in this case.
Divide the sum by the number of data points to find the mean: \(\frac{2 + 4 + 6 + 8}{4}\).
