Transcript of Math: Mean, Median, Mode, and Range

What is mean, median, mode and range? The mean is the average. You add and divide to find the average. Here is a example of average. 12+10+8+14= 44 44 divided by 4= 11 The way you do mode is you declare what occurred the most. M O D E A quick way to remember mode is... ost often number nly the same number is counted (12, 12, 13) on't just have to have one of the same numbers that you come across. nd by only haveing one group or two groups of the most often number. Range is when you subtract the high number to the low number. You take the low number and the high number. 21, 25, 33, 33, 36, 39, 47, 50 So you have 21 and 50. Then you subtract them. 21 50 - _____ 29 And you shoud get an anwer of 29! If you think, the word median sounds like middle. Well, it means the middle of the numbers. If we had the numbers.... 1, 5, 8, 13, 17, 19, 22 The number 13 would be the middle because I crossed the highest to the lowest (or you could do the rainbow) until you get 13. But what if you get TWO numbers at the same time!? 21, 25, 33, 33, 36, 39, 47, 50 There are two numbers in this one. All you do is add them up and then divide by two. I think your ready for the test!
