Range-Range is the difference between the lowest number and the highest number. Take, for example, math test scores. Let's say your best score all year was a 100 and your worst was a 75. Then the rest of the scores don't matter for range.
The mean is the average you're used to, where you add up all the numbers and then divide by the number of numbers. The median is the middle value in the list of numbers. To find the median, your numbers have to be listed in numerical order, so you may have to rewrite your list first.The mode is the value that occurs most often. If no number is repeated, then there is no mode for the list.The range is just the difference between the largest and smallest values.ut there is no middle number, because there are an even number of numbers. In this case, the median is the mean (the usual average) of the middle two values: (2 + 4) Ã· 2 = 6 Ã· 2 = 3. The mode is the number that is repeated most often, but all the numbers in this list appear only once, so there is no mode.
