Find the range of the data set provided:
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

Find the mean of the data set provided:
Explanation
In order to answer this question correctly, we need to recall the definition of mean:
Mean: The mean of a data set is the average of the numbers in a data set.
In order to calculate the mean we must first add up all of the numbers in the data set:
Next, we need to divide by the number of addends, or the number of numbers in the data set:
The mean for this data set is
