Example Questions

Example Question #95 : How To Find Range

Use the following data set to answer the question:

Find the range.

Possible Answers:

Correct answer:

Explanation:

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

So, given the data set

we can see the smallest number is 1 and the largest number is 9.  Now, we will find the difference.  We get

Therefore, the range of the data set is 8.

Example Question #411 : Isee Middle Level (Grades 7 8) Mathematics Achievement

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 find the smallest number 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 2 and the largest number is 10.  Now, we will find the difference.  We get

Therefore, the range of this data set is 8.

Example Question #102 : How To Find Range

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 #103 : How To Find Range

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 set

We can see the smallest number is 4 and the largest number is 9.  Now, we will find the difference.  So,

Therefore, the range of the data set is 5.

Example Question #101 : Data Analysis And Probability

Determine the range of the numbers provided:  

Possible Answers:

Correct answer:

Explanation:

The range of a set of numbers is the difference between the highest and lowest numbers.

The largest number is:  

The smallest number is:  

Subtract the numbers.

The answer is:  

Example Question #102 : Data Analysis And Probability

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 find the smallest number and the largest number. Then, we will find the difference of those two numbers. 

So, given the data set

we can see the smallest number is 4 and the largest number is 14. Now, we will find the difference. We get

Therefore, the range of the data set is 10.

Example Question #2 : Tables

Graph

The above circle graph shows the results of a school election. According to the rules, the election falls to the student who wins the majority of the votes; if no student wins a majority, the top two vote-getters will face each other in a runoff, with the winner being elected.

Which of the following is the result of this election?

Possible Answers:

Phelps and Wells will face each other in a runoff.

Phelps and Creighton will face each other in a runoff.

Phelps, Creighton, and Wells will face one another in a runoff.

None of the other choices is correct.

Phelps won the election outright.

Correct answer:

Phelps and Creighton will face each other in a runoff.

Explanation:

Since each of the six portions of the graph takes up less than half, no one won a majority. Therefore, there will be a runoff. The two largest portions are light blue (Phelps) and orange (Creighton), so Phelps and Creighton got the most and second-most votes, and they will face each other in a runoff.
