Mean,Median,and Mode

By : Arlene So Hello, I am here to explain how to find the mean, median, and mode.It's easy, all you have to do is follow the upcoming steps. Lets Start With ....

Mean Say you have a bunch of random

numbers. 4,2,4,6,9,8,7,11,8 4,2,4,6,9,8,7,11,8 59 9 The Steps First, add up all the numbers 4+2+4+6+9+8+7+11+8 = 59 Now count how many numbers there were originally. 4,2,4,6,9,8,7,11,8 <-- Nine numbers. Now divide the sum "59" by 9, because we are taking the sum and dividing it by the number of numbers. 59 ÷ 9 = 6.555 - Did you get that? The mean is 6.55, Tip : If there are endless numbers, just take the first 2 numbers after the decimal! Definition of Mean :

The mean is the average of the numbers: a calculated "central" value of a set of numbers. Here is a real life example :

Ms.Gorgeous had a math

test out of 10 people. These are the marks out of 100.... 50, 66, 78, 92, 41, 88, 99, 71, 91, 100 As explained a while ago,

first you add up all the numbers, then you count how many numbers there are in total, and you divide the sum by the number of numbers. The answer is 77.6 The average in Ms.Gorgeous's class is 77.6 Here is a video that explains "Mean" Median We are going to use the same numbers that we used for mean. Example : 2,2,3,7,4,6 The Median would be.... Definition:

The Median is the middle number of all the numbers in order by smallest to biggest 4,2,4,6,9,8,7,11,8 First, you put the numbers in order Now cross out the numbers

in this order : smallest, then biggest, then smallest, then biggest. The Median is

7 STEPS 4,2,4,6,9,8,7,11,8 2 , 4 , 4 , 6 , 7 , 8 , 8 , 9 , 11 put them in order.... 2 , 4 , 4 , 6 , 7 , 8 , 8 , 9 , 11 \ \ \ \ \ \ \ \ Tip : If there are 2 medians, which happens when there are an even amount of numbers.... you do this..... 2 , 2 , 3 , 4 , 6 , 7 / / / / 3 and 4 are the current median. What you have to do is add them up and then divide it by 2, because there are 2 medians.... 3 + 4 = 7......

7 ÷ 2 = 3.5 3.5 How to get the Median Real Life Example : These are the heights of the students in room 407. What is the class median. 4.5 , 5.1 , 6 , 5.8 , 5.6 , 4.7

5.1 , 5.7, 5.5 , 5.4 , 4.9 , 5 4.5 , 4.7 , 4.9 , 5 , 5.1 , 5.1 , 5.4 ,

5.5 , 5.6 , 5.7 , 5.8 , 6 The class median would be.... As explained a while ago

you order the numbers from

smallest to biggest, and then cross out the number from each side taking turns untill you end up with a number or 2 numbers. In this case there were 2 numbers. / / / / / / / / / / 5.1 and 5.4 are the two medians.

First add them up.... 5.1 + 5.4 = 10.5

Now divide it by two. 10.5 ÷ 2 = 5.25 5.25 feet. Mode All you have to

do is find out which number occur the most out of all numbers Like this... ...................... The Mode is the easiest out of Mean, Median, and Mode. Its just one simple step.... Eg: 4,4,5,6,7,8,9,2,4,3,2,9 The mode would be 4, because 4 showed up most often. But if there are no most

occurring number, then there

are no mode. If there is more than

one most occurring number

then put both/all of them. The "mode" is the value that occurs most often. If no number is repeated, then there is no mode for the list. Definition : Bonus : The range is usually stuck with the Mean, Median, and Mode topic. Range is just as easy as finding the Mode. All you have to do is look at the smallest number and the biggest number. if the smallest number in a set of numbers is 4, and the biggest is 10, then the range is : 4 - 10 Please enjoy this epic song I found... LOL Thank you for your patience!!!! ^.^ Real Life Example... Lina wants to know what shoe sizes do most people have. She collected a set of numbers from 10 people.. 5,6,9,9,8,8,8,5,10 What you have do is find the mode...Because the mode shows which shoe size most people have. In this case... The mode is 8

So the most had shoe size is

8. My Second Project.... 776 ÷ 10 = 77.6
