it is how much space your data stretches across, u find it by subtracting the lowest number from the highest.

In mathematics, the range of a function is the set of all "output" values produced by that function. Sometimes its is called the image, or more precisely, the image of the domain of the function.
In descriptive statistics, the range is the length of the smallest interval which contains all the data. It is calculated by subtracting the smallest observations from the greatest and provides an indication of statistical dispersion.
It is measured in the same units as the data. Since it only depends on two of the observations, it is a poor and weak measure of dispersion except when the sample size is large.
For a population, the range is more than twice the standard deviation.

range is the difference between the highest number and the lowest number. EX: (group of numbers) 5, 7, 13, 20, 3, 9, 10. 20-3=17. The range would be 17.

You put the numbers in the data from lowest to highest. You take the highest number and subtract the lowest number...that is your range.
Example: 14 8 19 12
8 12 14 19
19-8=11
Range: 11

In algebra, the range is the possible values for the dependent variable
In a graph or a standard equation, it is the possible values for y.
FYI the possible values for x or the independent variable is the domain.
In statistics the range is the distance between the largest and the smallest numbers in the list.
I hope this helps.

The range describes the limitations on the y-values of a function.
For example, the graph of y=x^2.
Domain is all real numbers. Range is from 0 to infinity. (the y-variables never get negative on that graph)

Range means the set of values of a function that you get by giving different values within the domain of the function for the variable in the function. The domain is the set of values you can give for the variable in the function.

In mathematics, the range of a function is the set of all "output" values produced by that function....thanks Wikipedia....
The range of the function is all of the "y" values. So, if you have a solution set for a function expressed as ordered pairs (x, y), then the range is all of the y values. Example: for the ordered pairs (1,5), (2,7), (3,9) the range would be 5,7,9 (and the domain would be 1,2,3)...okay, who cares about the domain...

if you have a list of numbers say one through ten you would right down that the range is 1-10

If your referring to the domain and range, the domain is the X axis and the range is the Y axis on a coordinate plan.

The defenition of range is "The set of y values in a relation is called the "range".
