In a set of data:
range = maximum - minimum
It is a very crude measure of spread. Better measures of spread are variance and standard deviation.

In stats, if i can remember, the range means the top number of a certain data set minus the bottom number of that same set equals the range of values available for that set. E.g. there are 20 students in a class with marks ranging from 70% to 90%. The range of this data set is 20%.

Alright. Range deals with a set of numbers. For example: 4,5,7,8,1,2,6,7. But, first, you have to put the set of numbers in order from least to greatest (in this case that would be, 1,2,4,5,6,7,7,8). Then you can find range. In order to do that, you would have to subtract the smallest number in the set (in this case, 1) from the largest number in the set (in this case, 8).
So, the range for this set would be:
8-1=9
So, it would be 9.
So, conclusively, here's the definition for range in statistics (stated in my own words):
Range: In a set of numbers ordered from lowest value to highest value, the smallest number in the set subtracted from the highest number in the set.
There you go, I'm glad I could help. :)

Range is the numerical interval which includes the values of samples from a distribution.

range can be found by substracting max-min.
