Example Questions
Example Question #1 : Range
Observe the following list of terms:
The range of this list of numbers is 
The range of this list of numbers is 10 which is obtained by doing 20-10.
This means that 20 and 10 are respectively the maximum and minimum values of the list of numbers.
Therefore x has to be a value between 10 and 20.
17 being the only value within this range it is therefore the right answer.
Example Question #1 : Range
For a set of numbers 
and the set has the following values:
Determine the value of 
{6,6,6,7,7,7,7,13,13}
median=7 so b=7
mean=8 so the sum of the set is 72.
72-4(7)=44
44=3a+2c
Range=7 so c-a=7
44=3a+2(a+7)
a=6 and c=13.
Example Question #581 : Statistics And Probability
Given the set of test scores, what is the range?
The range is the difference between the smallest number and the largest number. The smallest value is 77, and the largest is 98.
98 – 77 = 21
Example Question #6 : How To Find Range
The range of the following data set is 18. What is a possible value for 
Cannot be determined
Arrange the known values in the set in numerical order: {–5, –2, 1, 3, 5, 7, 7, 10}. The range is the difference between the largest value and smallest value.
x must be either the largest or the smallest value in the set.
range = x – smallest value
18 = x – (–5)
18 = x + 5
13 = x
OR
range = largest value – x
18 = 10 – x
8 = –x
–8 = x
Example Question #1 : How To Find Range
The above chart shows a specific week of work at an advertising firm. What is the range of the hourly rates of the workers?
The range is difference between the largest value and the smallest value.
Example Question #1 : How To Find Range
What is the range of the set 
The range is defined as the difference between the highest and lowest numbers in a set. Here, the highest number is 
Therefore, the range is
Example Question #5 : Range
Find the range of the set:
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 as follows.
Example Question #1 : Data Properties
Find the range of the set:
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,
Example Question #72 : Basic Statistics
Find the range of the set:
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,
Example Question #81 : Basic Statistics
Find the range of the following set of data.
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,
