    O.k Mean= The average, adding all the numbers and then dividing them by the amount of numbers Median = the middle number when the numbers are listed from smallest to biggest Mode=Is the number listed the most Range= the biggest number - the smallest number

    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.

    yes you divide after you add you divide it by the number of numbers you've added up. so if you had 20 and 30 you add to 50 and divide by 2 because there are two numbers 20, and 30.
