what does the range mean in math?

IM PRETTY SURE ITS THE MAXIUM MINUS THE MINIMUM

Let's define each of the words and give an example.

Consider the set of numbers 80, 90, 90, 100, 85, 90. They could be

math grades, for example.

The MEAN is the arithmetic average, the average you are probably used

to finding for a set of numbers - add up the numbers and divide by how

many there are: (80 + 90 + 90 + 100 + 85 + 90) / 6 = 89 1/6.

The MEDIAN is the number in the middle. In order to find the median,

you have to put the values in order from lowest to highest, then find

the number that is exactly in the middle:

80 85 90 90 90 100

^

since there is an even number of values, the MEDIAN is

between these two, or it is 90. Notice that there is

exactly the same number of values ABOVE the median as

BELOW it!

The MODE is the value that occurs most often. In this case, since

there are 3 90's, the mode is 90. A set of data can have more than one

mode.

The RANGE is the difference between the lowest and highest values.

In this case 100 - 80 = 20, so the range is 20. The range tells you

something about how spread out the data are. Data with large ranges

tend to be more spread out.

There are a range of meanings for range in math, from the smallest to the largest, this one is middle sized.
