Explanation:

The range is the difference of the largest and smallest numbers.

The largest number is 11.

The smallest number is negative nine.

Subtract both quantities.

The answer is:  

Example Question #14 : Other Data Calculations

Use the following data set of test scores to answer the question:

Find the range.

Possible Answers:

Correct answer:

Explanation:

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

So, given the set

we can see the smallest number is 78 and the largest number is 95. Now, we will find the difference.

Therefore, the range of the data set of test scores is 17.

Example Question #15 : Other Data Calculations

A Science class took an exam. Here are the scores of 9 students:

Find the range.

Possible Answers:

Correct answer:

Explanation:

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

So, given the set

we can see the smallest number is 76 and the largest number is 93. Now, we will find the difference. We get

Therefore, the range of the data set is 17.

Example Question #16 : Other Data Calculations

A class took a Math exam.  Here are the test scores of 10 students.

Find the range.

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, we will find the smallest and 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 77 and the largest is 99. Now, we will find the difference. We get

Therefore, the range of the data set is 22.

Example Question #17 : Other Data Calculations

The answer is:  

Example Question #20 : Other Data Calculations

A class took a Math exam. Here are the test scores of 8 students.

Find the range.

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, we will find the smallest and 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 76 and the largest is 91. Now, we will find the difference. We get

Therefore, the range of the data set is 15.
