um i hope i am doing this right so umm how does this work..............OH I GOT IT

Mean, Median and Mode

The three ways of finding the average of a group of numbers.


MEAN- the average number

To find mean in a group of numbers you take the numbers and add them all together ex. 10 13 14 17.

STEP 1 STEP 2
10
13
14 10 divided by 4 = 13.5
+17=
54

You then take the Sum and divide it by the amount of numbers you used to get the sum. Ex 54 divided by 4 = 13.5
and that is your average 13.5


MEDIAN- the middle number when you allin sp.x a group of numbers.

Take several numbers ex. 2 4 1 3 6 and you arrange them from smallest to largest

STEP 1

1 2 3 4 6


and then find the middle number in the row and thats your median
EX 2 if you don't have a odd number of numbers ex 1 2 3 4 5 6 you allign them in order like before and take the 2 middle numbers and add them together and divide the sum by 2

1 2 3 4 5 6 in this case 3 and 4 = 7 divided by 2 = 3.5 and that is your median

MODE- the most amount of numbers

in a group of numbers you find the most common number
ex 2 4 5 4 3 1 so the mode in this would be 4 because there are 2 4s and that is how you find the mode
or
if there are two numbers that are more common like 22 33 4 5 the mode would be BOTH 2 and 3.

so ya this is my first blog and I hope you like it ps please comment on it yay

My Long Awaited Blog Post From Before Christmas

Interest
Today in class we learned about interest, to find the interest of any number you must multiply the principal by the rate.

500 = Principal
.12 = Rate
1 = Time

500 x .12 = 60.00 x 1 = 60.00 = The interest is 60.00
