The range is calculated by taking the highest value and subtracting the lowest value. With data sets, you must always include the zeros! :

The mean is calculated by summing all values in the data set and dividing by the total number of data points. Again, you must include the zeros:

The range of a dataset is the difference of the lowest number from the highest number in the set.

There are two unknown variables in the dataset, .  

We cannot assume that the dataset is in chronological order, and we cannot assume that  and  are the greatest numbers in the set.

Because the variables are not defined, we do not have enough information to solve for the range.

The answer is:  

To solve, simply use the formula for the range. Thus,

To find the range, simply subtract the smallest number from the largest. Thus,

This problem is asking us to solve for the range for the students' data set. This can easily be solved for once we take into account that range is merely the difference between the greatest number in the set and the lowest. 

In order to easily see which number is the lowest and which is the greatest, we can first organize our data set from smallest to greatest.

Now we can easily identify 1.7 being the smallest number and 6.5 being the greatest in this data set. Now we may take the difference of these numbers and solve for the range.

This problem is asking us to solve for the range of Tom's speed. This can easily be solved for once we take into account that range is merely the difference between the greatest number in the set and the lowest. 

In order to easily see which number is the lowest and which is the greatest, we can first organize our data set from smallest to greatest.

Now we can easily identify 62 being the smallest number and 88 being the greatest in this data set. Now we may take the difference of these numbers and solve for the range.

This problem is asking us to solve for the range for the data set consisting of how many apples each student picked. This can easily be solved for once we take into account that range is merely the difference between the greatest number in the set and the lowest. 

In order to easily see which number is the lowest and which is the greatest, we can first organize our data set from smallest to greatest.

Now we can easily identify 1 being the smallest number and 8 being the greatest in this data set. Now we may take the difference of these numbers and solve for the range.

This problem is asking us to solve for the range of the grades. This can easily be solved for once we take into account that range is merely the difference between the greatest number in the set and the lowest. 

In order to easily see which number is the lowest and which is the greatest, we can first organize our data set from smallest to greatest.

Now we can easily identify 55 being the smallest number and 98 being the greatest in this data set. Now we may take the difference of these numbers and solve for the range.

The range is the difference between the highest and lowest numbers in the data set.

The highest number is 10.  The smallest number is negative four.  Subtract both numbers.

The answer is:  

Find the range of the following data set:

Whenever we are working with a data set, it can be helpful to put the terms in order:

Now, to find the range, we need to find the difference between our largest and least values:

So our range is 83
