Find the range of the following data set:

Explanation

Find the mode of the following data set:

First, let's rearrange our numbers in increasing order:

Next, identify the range by subtracting the first number from the last number:

So our range is 185

Explanation

In order to answer this question correctly, we need to recall the definition of range:

Range: The range of a data set is the difference between the highest value and the lowest value in the set.

In order to find the range, we need to first organize the data from least to greatest to find the lowest and highest values:

Next, we can solve for the difference between the highest value and the lowest value:

The range for this data set is

3

Find the range in this set of numbers:

Explanation

First, order the numbers from least to greatest:

Then, subtract the smallest number from the largest:

Answer: The range is 11.

4

A Math class took an exam. Here are the scores of 11 students:

Find the range.

Explanation

To find the range of a data set, we will find the smallest and the largest number. Then, we will find the difference of those two numbers.

So, given the set

We can see the smallest number is 76 and the largest number is 98. Now, we will find the difference. To find the difference, we will subtract the two numbers. We get

Therefore, the range of the data set is 22.

5

8

Use the following data set to answer the question:

Find the range.

Explanation

To find the range of a data set, we will first find the smallest and the largest number. Then, we will find the difference of these two numbers.

So, in the data set

we can see the smallest number is 2 and the largest number is 9. Now, we will find the difference. To find the difference, we will subtract the two numbers. We get

Therefore, the range of the data set is .

10

Use the following data set to answer the question:

Find the range.

Explanation

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 .
