Find the range of the set:

Possible Answers:

Correct answer:

Explanation:

To find the range of a set subtract the smallest number in the set from the largest number in the set:

The largest number is in green: 

The smallest number is in blue: 

Therefore the range is their difference,

Example Question #81 : Basic Statistics

What is the range of the following data set?

Possible Answers:

Correct answer:

Explanation:

What is the range of the following data set?

The range is found by taking the difference between the largest and smallest value in the data set.

Largest: 103

Smallest: 1

So our range is 

Example Question #83 : Basic Statistics

Find the range of the following dataset:  

Possible Answers:

Correct answer:

Explanation:

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

The largest number in this set is .  The smallest number in this set is .

Example Question #43 : Basic Statistics

Find the range of the dataset:  

Possible Answers:

Correct answer:

Explanation:

The range is the difference of the highest and lowest number.  In order to determine the highest and lowest fraction in the dataset, we must convert each fraction to a like denominator and compare.

The least common denominator for these fractions is .  Reconvert all fractions with a denominator of 24 in order to compare numerators.  Multiply the numerators with what was multiplied on the denominator to get the least common denominator.

The largest number is:   or 

The smallest number is:   or 

Subtract these numbers.

The range is:  

Example Question #44 : Basic Statistics

Find the range of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the range of the following data set:

The range is simply the distance between the largest and smallest value.

Let's begin by finding our two extreme values:

Largest: 2952

Smallest: 1

So our range is 2951

Example Question #84 : Basic Statistics

Find the range of this data set:

Possible Answers:

Correct answer:

Explanation:

Find the range of this data set:

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

Next, find the difference between our largest and smallest number. This is our range:

So our answer is 922

 

Example Question #45 : Basic Statistics

Find the range of the following data set:

Possible Answers:

Correct answer:

Explanation:

Find the range of the following data set:

Let's begin by putting our data in increasing order:

Next, find the difference between our first and last numbers. This will be our range.

So our answer is  566

Example Question #46 : Basic Statistics

Mrs. Potter gave a test to her Algebra II class, and the scores were as follows:

What is the range of the test scores? 

Possible Answers:

Correct answer:

Explanation:

The range is simply the maximum value minus the minimum value. The highest test score was , and the lowest was

, so the range of the test scores was 27.
