Example Questions
Example Question #1 : How To Find Range
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 #2 : 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 #5 : 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 #6 : 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 #1 : How To Find Range
In the set of numbers, what is the range?
To determine the range of this data set, take the largest number and subtract it with the smallest number.
The largest number in the set is ten.
The smallest number in the set is 
Subtract both numbers.
Example Question #2 : How To Find Range
Find the range of the following set of numbers.
Subtract the lowest number (4) from the highest (52) to get 48.
Example Question #11 : How To Find Range
In the field of hematology, a patient's blood oxygen content is considered "stable" if the readings taken over a period of 24 hours have a range no larger than 4.5. A day's readings for a patient are below. Is this patient's blood oxygen content stable?
Yes, the range is less than 4.5.
No, the range is more than 4.5.
No, the range is less than 4.5.
There is not enough data to answer the question.
Yes, the range is more than 4.5.
Yes, the range is less than 4.5.
To compute range, we must first identify the least and greatest values in a data set. The easiest way to do this is to order the set:
Range is found by the equation 
Thus, our range is 
Since 
Example Question #11 : How To Find Range
An ecosystem is considered to have "mild" climate if the range of its temperatures over a calendar year is less than 
Average monthly temperatures in Celsius for a sample climate are given below (December through November). What statement can be made about the climate of this sample?
The climate is both moderate and severe.
The climate is mild.
The climate is severe.
There is not enough data to answer the question.
The climate of the sample is moderate.
The climate of the sample is moderate.
In this problem, finding the range of the sample is as simple as subtracting the lowest temperature value, 
Since 
Example Question #11 : How To Find Range
Using the data above, calculate the range.
The range is found by finding the difference between the highest and lowest values in a given set. In this set the highest number is 
Example Question #581 : Statistics And Probability
Using the data above, find the range.
To find the range of a data set, we must first identify the highest value given: 
Next, we identify the lowest value given, 
Now we must find the interval between these two numbers, 
This is our range. Note that the data piece value of
