//Example : 13, 8, 22, 13, 13, 30 }// NUMERICAL ORDER: 8, 13, 13, 13, 22, 30

**Mean**

 * Also known as the average.

- To find the mean, you find the sum of all data by adding the numbers. Divide the sum by the number of pieces of data. //ex: 8 + 13 + 13 + 13 + 22 + 30 99 divided by 6 = __**16.5**__// **//( mean )//**

**Median**

 * The middle number in a set of data.

- If there are two middle numbers, you add them up and divide the sum by 2. //ex:// //8, 13, 13, 13, 22, 30 } 13 + 13 = 26// //26 ÷ 2 = **__13 ( median )__**//

**Mode**

 * The number that occurs or shows up the most.

//ex: 8, 13, 13, 13, 22, 30 } **__13 is the ( mode )__**//


 * //__QUESTION 1__//** Find the mean median and mode : 15, 9, 22, 25, 7, 22 //* REMEMBER TO: Arrange in numerical order first ( smallest to largest )//

**THEIR ANSWER**
MEAN: 1.) 7, 9, 15, 22, 22, 25 2. ) 7 + 9 + 15 + 22 + 22 + 25 = 100 3.) 100 divided 6 = 16.6 ROUND OFF > 17.0

MEDIAN: 1.) 7, 9, 15, 22, 22, 25 2.) 15 + 22 = 37 3.) 37 divided by 2 = 18.5

MODE: 1.) 7, 9, 15, 22, 22, 25 2.) 22

__**//QUESTION 3//**__ Is taking 15% off a given item and then an addtional 10% off the reduced price the same as taking 25% off the original price ? Why or Why not ?

>> ANSWER

THEIR ANSWER
ANSWER: $50 50 x 0.15 = 7.5 50 - 7.5 = 42.5

42.5 less 10% ($4.25) 42.5 - 4.25 = 38.25

50 x 0.25 = 12.5 50 - 12.5 = 37.5

No because 25% is straight forward than the other one.
