years
The youngest of John and his siblings is his younger sister, who is . The oldest of John and his siblings is his older sister, who is . To find the range we need to subtract the lowest value from the highest value.
This gives us a range of,
years.
Example Question #1 : Range
Robert has a data set consisting of the following numbers:
What is the range of the data set?
The correct answer is 725. The range of any data set can be obtained by subtracting the smallest number from the largest number.
In this case, the smallest number is 28 and the largest number is 753.
The following subtraction problem gives us the answer:
.
Example Question #3 : Range
Karen plays on her school's basketball team. She keeps track of the number of points she scores in each game. For the past 6 games, she scored 23 points, 10 points, 34 points, 9 points, 12 points, and 11 points. What is the range for the number of points she scored over the past 6 games?
To find the range, place the numbers in numerical order:
Then, subtract the smallest value from the largest value.
Example Question #2 : Range
Jessica wanted to keep track of how well she was doing in her basketball games, so she started recording the number of points she scored each game. In her past six games, she scored points, points, points, points, points, and points. What is the range of the number of points Jessica has scored in the past six games?
To find the range of a set of numbers, you need to first find the smallest and the largest numbers.
In Jessica's case, our smallest data point is 5 and the largest is 31.
Then, to find the range, subtract these two numbers.
Example Question #4 : Range
Loretta tracks how much money her ice cream shop makes in a week. On Monday, she made . On Tuesday, she made . On Wednesday, she made . On Thursday, she made . On Friday, she made . On Saturday, she made . On Sunday, she made . What is the range of the money she made in this given week?
To find the range, you need to first find the largest and the smallest number in the data set.
In this case, the largest number is 3019 and the smallest number is 918.
To find the range, subtract the smallest number from the largest.
Example Question #3 : Range
In a calculus class with students, the highest score on the most recent test was a while the lowest score on the most recent test was a . What is the range on the most recent test?
To find the range of a set of numbers, subtract the smallest number from the largest number.
Example Question #6 : Range
Observe the following table:
Client | Age |
Marsha | 14 |
Tom | 13 |
Alice | 65 |
Brandy | 34 |
Candy | 23 |
James | 43 |
Brady | 19 |
Find the range for the ages of the clients in the table?
Let us start by identifying the maximum and minimum values of the list of values.
The maximum is 65 and the minimum is 13.
The range is computed by substracting the minimum from the maximum, which gives us:
Example Question #5 : 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 as follows.
Example Question #6 : 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 #7 : 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,
