Question

In a recent survey, 8 college graduates were each asked for the number of hours they work each week. Here is a list of the responses. 50, 52, 36, 46, 41, 36, 56, 65 Find the range of the data set.

Answer 1

add all of them together and divide by 8 (total number of college's)

Answer 2

Answer: 29

-------------------------

To get this answer, you subtract the largest and smallest values, which are also known as the max and min respectively

Range = Largest Value - Smallest Value

Range = Max - Min

Range = 65 - 36

Range = 29

If it helps, sort the data in order from smallest to largest to get this list of values: {36, 36, 41, 46, 50, 52, 56, 65} so you can see the min and max easier. The range is basically the spread of the data (more or less). The larger the range, the more spread out the data values are.
