Front

How do you calculate the mean of the following numbers: 36, 42, 28, 52, 48, 36, 31?

Back

Mean = (36 + 42 + 28 + 52 + 48 + 36 + 31) / 7 = 39.

What is the minimum value in a dataset?

Back

The minimum value is the smallest number in a set of data.

Front

How do you find the maximum value in a dataset?
