Example Question #104 : Data Analysis

Use the following data set to answer the question:

Find the range.

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, we will first find the smallest and the largest number within the set.  Then, we will find the difference of those two numbers.

So, given the data set

we can see the smallest number is 2 and the largest number is 9.  So, we will find the difference.  We get

Therefore, the range of the data set is 7.

Example Question #105 : Data Analysis
