Example Question #71 : Range
Use the following data set to answer the question.
Find the range.
To find the range of a data set, we will take the smallest and largest number and calculate the difference of those two numbers.
So, given the data set
we can see the smallest number is and the largest number is . Now, we will find the difference. We get
Therefore, the range of the data set is .
Example Question #382 : Isee Middle Level (Grades 7 8) Mathematics Achievement
Find the range of the following data set:
Find the range of the following data set:
Let's begin by ordering our data set from least to greatest.
To find the range, we need to find the difference between the greatest and least values.
So our answer is 110
Example Question #72 : How To Find Range
Use the following data set to answer the question.
Find the range.
To find the range of a data set, we must first find the smallest number and the largest number within the set. Once we do that, we must find the difference of those numbers, or subtract those two numbers.
So, given the set
we can see the smallest number is and the largest number is . Now, we will find the difference.
Therefore, the range of the data set is .
Example Question #71 : Range
If the middle number of a set is increased, how is the range affected?
Decreases
No effect
Cannot be determined
Increases
Cannot be determined
The reason that this cannot be determined is that there is no specific increase given in the problem. The minimum number and maximum number are used to find the range. If the middle number remains below the maximum number, the range remains the same. If the original middle number is increased to the point of being larger than the original maximum, the range will increase.
Example Question #72 : Range
Find the range of the following data set:
Find the range of the following data set:
First, let's reorder our data set:
Now, simply find the difference between our largest and smallest numbers:
So our answer is 77
Example Question #74 : Data Analysis
Use the following data set to answer the question.
Find the range of the data set.
To find the range of a data set, we will first locate the smallest and the largest numbers within the set. Once we do that, we will then find the difference of those two numbers. To find the difference, we simply subtract the numbers.
So, given the set
we can see the smallest number is and the largest number is . Now, we will find the difference.
Therefore, the range of the data set is .
Example Question #76 : Data Analysis And Probability
Use the following data set to answer the question.
Find the range of the data set.
To find the range of a data set, we will first locate the smallest and the largest numbers within the set. Once we do that, we will then find the difference of those two numbers. To find the difference, we simply subtract the numbers.
So, given the set
we can see the smallest number is and the largest number is . Now, we will find the difference.
Therefore, the range of the data set is .
Example Question #73 : Range
Find the range of the following data set.
Find the range of the following data set.
To begin, put the terms in ascending order:
Next, find the difference between the first and last numbers:
So, our range is 333
Example Question #81 : Data Analysis
Use the following data set to answer the question:
Find the range.
To find the range of a data set, we will find the smallest number, then we will find the largest number, and we will calculate the difference of those numbers. So, given the set
we can see the smallest number is and the largest number is . Now, we will find the difference. To find the difference, we will subtract. We get
Therefore, the range of the data set is .
Example Question #82 : Data Analysis
Use the following data set to answer the question:
Find the range.
To find the range of a data set, we will find the smallest and the largest numbers and then find the difference of those numbers.
So, in the set
we can see the smallest number is 2 and the largest number is 10. So, we will find the difference. We get
Therefore, the range of the data set is 8.
