Mean Median and Mode

- is when you add all your numbers together and divide it by the sum of data
 * Mean**

- is the middle number - if you have two middle numbers, you add them up and divide it by two
 * Median**

- is the number that appears the most - if there is two numbers that appear the most, both are the mode - 1, 2, 3, 4, 5 <<< this does not have a mode
 * Mode**

1. Find the mean, median and mode for:

 * remember to put it in numerical order

6, 10, 24, 5, 18, 5, 10, 5

answer here please: numerical order : 5, 5, 5, 6, 10, 10, 18, 24 mean : 5 + 5 + 5 + 6 + 10 + 10 + 18 + 24 83 / 8 = 10.375 median : 6 + 10 16 / 2 = 8 mode : 5

- is a number that times itself example: the number 4's square root is 2 ( 2 x 2 ), square root of 81 is 9 ( 9 x 9)
 * Square Root**

- any square that has the same whole number for all sides
 * Perfect Square**

example: find the square root for 38 <<< that is not on the square root chart number before 38 is 36 number after 38 is 49
 * HINT** : If you have to find a square root for a number that is not on the square root chart, you have to look at the number before and after it. Then you find the square root for the before and after number. Then that must mean that the square root of the number that isn't on the chart is in the middle of the before and after number.

36 = 6 x 6 38 = 6. ? x 6. ? 49 = 7 x 7

example: fraction for 38 <<< square root for this number is 6. ? <<< 6 will be the whole number for the fraction number before: 36 number after: 49
 * To find the fraction** - this is for the number that is not on the square root chart. You have to take the whole number, then you take the before number and subtract it from the after number. The answer that you get will be your denominator. Then you count, starting from the number after your before number, until you reach the number that you are finding the fraction for. When you reach it, put the number that you counted when you reached the number to be the numerator of your fraction. Your fraction should be a mixed fraction.

49 - 36 = 13 <<< 13 is the denominator 37 = 1 38 = 2 <<< 2 is the numerator

6 2/13 is the fraction

 * 2. What is the square root for 48 ?**
 * show your work and show the fraction

Write here:

before number : 36 = 6 x 6 after number : 49 = 7 x 7 48 = 6.? x 6.? 6 >> whole number 49 - 36 = 13 >> denominator 48 = 12 >> numerator 37 = 1 38 = 2 39 = 3 40 = 4 41 = 5 42 = 6 43 = 7 44 = 8 45 = 9 46 = 10 47 = 11

48 = 12
49 = 13

 * 3. Is taking 15% off a given item and then an additional 10% off the reduced price the same as taking 25% off the original price? Why or why not?** **Choose an easy number to answer this question.**

Write here: No it is not the same because:

$100 - 15% = $85 15% = $15 $85 - 10% = $76.50 10% = $8.50

$100 - 25% = $75 25% = $25

$75 is not the same as $76.50
