set of numbers for examples. 18,8,3,5,3,6,10 __Mean:__ To find the mean you add together every number in a set of data. Then you take that sum of all data and divide it by the amount of data you have. It's also the same thing as the average. --Example-- __3+3+5+6+8+10+18=53__ 7 53/7=7.57is the mean note: It is easier if you put your set of numbers all in numerical order. __Median:__ The median is the middle number of the set of data. --Example-- 3,3,5,6,8,10,18 if you pair each number it would be easier to find the median. 3-18 - 3-10 - 5-8 // 6 is the only number that is not paired. So in that case 6 is the middle number.
 * __1.Mean, Median and Mode-__**

But if there is 2 numbers that are left out you add the to middle number and then divide by 2. That should be the answer. __Mode:__ The mode is the most common number. There can also be more than 1 mode. And if there is no common number that is called __NO MODE.__ --Example-- 3,3,5,6,7,8,9,10 3,3,4,5,6,7,7,8,9,10 3,4,5,6,7,8,9,10,11 the 3's would be the mode. The 3's and 7's are the mode. This is the No Mode when the is no common number.

Find the mean, median and mode for this set of data. 4,7,2,9,4,18,20,18

__**2.Square Roots-**__ Perfect Square: a whole number that can be multiplied by itself. No decimals. Square Root: a number multiplied by itself.

What is the square root of 45?

__**3.Percents-**__ To find the percent of any number.. --Example-- find 12% of 100

-- take number your trying to find the percent of and divide by 100. (100/100=1) -- then multiply that by the number you want to find. (100x12=12) -- so 12 is 12% of 100.

Is taking 15% of a given item and then an additional 10% of the reduced price the same as taking 25% of the original price? Why or Why not?
