What the range in maths for kids?

In a function, the "range" is the set of all possible values of a function for the values of the variable, or the values that result when a function takes in the domain.

For example, the function y=2X+3, the range is all real numbers.

In statistical data, the range is the difference between the smallest value and the largest value in the set. To find range, you subtract the smallest value in the data set from the largest value.

For example, this data set:

73, 77, 84, 87, 89, 91, 94

The range is the difference of the smallest value and the largest value, so 94-73=21. The range is 21
