Question 1

How do I calculate the range?

Accepted Answer

The range is the difference between the maximum and minimum values in your data set. Formula: Range = Maximum − Minimum. For example, the range of 3, 7, 8, 12, 15 is 15 − 3 = 12.

Question 2

What is the midrange?

Accepted Answer

The midrange is the average of the maximum and minimum values: (Max + Min) ÷ 2. It gives a rough measure of the center of your data.

Question 3

What does a large range mean?

Accepted Answer

A large range means the data is spread out widely — the difference between the largest and smallest values is big. A small range means the numbers are clustered closely together.

Question 4

Is range the same as standard deviation?

Accepted Answer

No. Range only considers the two extreme values (max and min), while standard deviation considers how far every number is from the mean. Standard deviation is a more robust measure of spread.
