What are the uses of range?

The RangeThe range is simple to compute and is useful when you wish to evaluate the whole of a dataset.The range is useful for showing the spread within a dataset and for comparing the spread between similar datasets.

What are the uses of mean?

The mean can be used to represent the typical value and therefore serves as a yardstick for all observations. For example, if we would like to know how many hours on average an employee spends at training in a year, we can find the mean training hours of a group of employees.

How is mean used in real life?

The mean is often used in research, academics and in sports. When you watch a baseball game and you see the player’s batting average, that number represents the total number of hits divided by the number of times at bat. In other words, that number is the mean.
