Answer:

3) The range of a set of data is the difference between the highest and lowest values in the set. To find it, first order the data from least to greatest. Then subtract the smallest value from the largest value in the set.

4) The arithmetic mean is the simplest and most widely used measure of a mean, or average. It simply involves taking the sum of a group of numbers, then dividing that sum by the count of the numbers used in the series.
