What is the range of the following data set?

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

Find the range of the set:

Explanation

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

${\color{Blue}15}, 15, 19, 21, 22, 24, 26, 27, 29, 31, 33, {\color{Green}36}$

The largest number is in green:

The smallest number is in blue:

Therefore the range is their difference,

John is years old. He has a younger sister who is , a younger brother who is , and an older sister who is . What is the range of John and his siblings' ages?

years

Explanation

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.

Robert has a data set consisting of the following numbers:

What is the range of the data set?

Explanation

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:

Find the range of the following dataset:

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 .

Subtract these numbers.

Find the range of the set:

Explanation

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

${\color{Blue} 4}, 5, 6, 12, 15, 18, 19, 23, 26, 27, 31, 39, {\color{Green} 41}$

The largest number is in green:

The smallest number is in blue:

Therefore the range is as follows.

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?

Explanation

To find the range, place the numbers in numerical order:

Then, subtract the smallest value from the largest value.

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?

Explanation

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.

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?
