mean, median, and mode

MEAN:
Mean is when you need to find a certain average of something what you do is add all the numbers together that are in the list and then divide it by the amount of numbers in your list for example.

Step one:
45, 13,78,53,36
Step two:
45
13
+78
53
­_36_
225

Step three:
_45__ the average number is
45
5 l 225
_20
25

MEDIAN:
Median is the middle number in a set of numbers after you put them in order from lest to greatest for example.

Step one:
67,69,100, 3,45,21,7
Step two:
3, 7, 21, 45 ,67, 69, 100

Step three:

3, 7, 21, 45, 67, 69, 100

Or if you have a an even amount of numbers you can have two medians.


MODE:
Mode is when there is a list of numbers or object and there is two or possibly more of one of the things on the list for example.




As you can see there are two Nintendo wii’s that means it is the mode.
