Example Question #661 : Statistics And Probability

Find the range of the following data set:

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, you find the difference between the largest and the smallest number.  Given the data set

1, 3, 6, 4, 1, 6, 1, 7, 11

The smallest number is 1 and the largest is 11.  The difference of these two numbers is 10.

Therefore, the range equals 10.

Example Question #662 : Statistics And Probability

Find the median of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the range of the following data set:

To begin, let's put our data in increasing order:

Now, our median will simply be the middle term.

In this case, our median is 76

Example Question #663 : Statistics And Probability

Find the range of the dataset:  

Possible Answers:

Correct answer:

Explanation:

The range is the difference between the highest and lowest numbers in the data set.

The highest number is 6.  The smallest number is negative eight.  Subtract both numbers.

The answer is:  

Example Question #664 : Statistics And Probability

Find the range of the following data set:

4, 2, 7, 8, 8, 2, 8, 11, 7

If necessary, round your answer to the nearest whole number.

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, you find the difference of the smallest and largest number.  Given the data set

4, 2, 7, 8, 8, 2, 8, 11, 7

the smallest number is 2 and the largest number is 11.  The difference of these two numbers is

Therefore, the range of the data set is 9.

Example Question #665 : Statistics And Probability

Find the range of the dataset:  

Possible Answers:

Correct answer:

Explanation:

The range is the difference of the highest and the lowest numbers.

The highest number is 74.  The lowest number is negative three.  

The range is .

Example Question #2091 : Algebra 1

Find the range of the following set of numbers:

1,1,3,7,7,8,9,12,15

Possible Answers:

Correct answer:

Explanation:

To find the range, simply subtract the smallest number from the largest. Thus,

Note that even thought he smallest number, 1, appears twice in our set, we don't subtract it twice from the largest number.

Example Question #666 : Statistics And Probability

Find the range of the following dataset:  

Possible Answers:

Correct answer:

Explanation:

The range is the difference between the highest and lowest numbers.

The highest number is 7.  The lowest number is negative nine.  

Subtract these numbers.

The range is:  

Example Question #667 : Statistics And Probability

Find the range of the following data set:

10, 9, 11, 10, 8, 4, 10, 7, 8

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, we calculate the difference of the smallest and the largest number within the set.  Given the set

10, 9, 11, 10, 8, 4, 10, 7, 8

the smallest number is 4 and the largest number is 11.  The difference of these two numbers is 7.  Therefore, the range of this data set is 7.

Example Question #668 : Statistics And Probability

Find the range of the following data set:

13, 4, 6, 3, 9, 3, 11, 11, 3

Possible Answers:

Correct answer:

Explanation:

To find the range of a data set, find the difference of the smallest and largest number.  Given the data set

13, 4, 6, 3, 9, 3, 11, 11, 3

the smallest number is 3 and the largest is 13.  The difference of these two numbers is 10.  Therefore, the range of the data set is 10.

Example Question #669 : Statistics And Probability

What is the range of the dataset?  

Possible Answers:

Correct answer:

Explanation:

The range is the difference of the highest and lowest numbers in the dataset.  The x and y variables are not defined. This means that they can represent any number. 

Therefore, we do not know what values are the highest and lowest in the dataset.

The answer is:
