§ Date Set - a list of numbers § Mean – average of list of numbers § Median - the middle number § Mode – number that occurs most often § Sum - refers to addition, for example they will ask you like what is the sum of 12 and 22. They simply mean you must add those two numbers together § Total - the whole amount of something § Amount of Number - how many numbers to you have in your list § Most Common - something that is the same § Odd Number – an odd number is a number that can’t be divide by 2 for example 1, 3, 5, 7, 9 , 11, 13, 15, § Odd Count – it means that when you count the amount of numbers its an odd number § Even Number – a number that can be divide by two § Even Count - it mean that when you count how many number is your list, the number that you count is even § Least – small, little § Greatest – big, large

- Mean, Median and Mode - Notes will be taken while watching You. Tube video, your notes should have : - 2 notes on mean - 2 notes on median - 2 notes on mode - Last : Which frog did you like the best?

What did you guys learn from The Mean Frogs?

WHERE DO WE MEAN, MEDIAN, AND MODE IN TODAY’S WORLD? Nintendo ex. Pokemon Electronic Arts –ex. FIFA series, Star wars series Sony Computer Entertainment- ex. Play station Ubisoft ex. Just dance series Naughty Dog Inc. ex. Jak and Daxter Microsoft Corporation ex. Xbox All of these are companies that make new items for people, the leaders in each company need to gather information on the people that would buy their products, therefore they look how successful their product would be by gathering data. They look if boys or girls would most likely buy the product, or if young or older people are most likely to buy it.

MEAN The MEAN of a data set is the SUM of the numbers DIVIDED by the total amount of numbers in the data set

, You count how many numbers you got

Step 3: DIVIDE the SUM by the TOTAL AMOUNT OF NUMBERS in your data set. The SUM OF YOUR DATA SET THE TOTAL AMOUNT OF NUMBERS IN YOUR DATA SET MEAN 30 ÷ 5 = 6 Your MEAN is 6

Practice #1 Find the Mean:

Practice #2 Find the Mean

Our Data Set: 6, 11, 15, 13, 2 Step 1: Arrange the data from LEAST to GREASTEST Least 2, Greatest 6, 11, 13, 15

Step 2: Find the MIDDLE number : 2, 6, 11, 13, 15 11 is your MEDIAN This number is your MEDIAN When having an ODD COUNT of numbers

LET ME SHOW YOU WHAT I MEAN. . . DATA SET WITH EVEN AMOUNT OF NUMBERS 4, 6

Step 3 : Take the two numbers in the middle and add them together and divide by 2 4, 6

Practice 3: Data Set: 8, 6, 2, 5, 6, 8, 9 Step 1: Arrange numbers from least to greatest Least 2, Greatest 5, 6, 8, 9 6 is the number in the middle therefore it is the median Answer: 6

Practice 1:

MODE There can be More than one!

Practice 1: 8, 10, 14, 8, 17, 20 Step 1: Arrange from Least to Greatest Least Greatest 8, 8, 10, 14, 17, 20 Step 2: Find the number that occurs the most often 8, 8, 10, 14, 17, 20 Since 8 and 20 appears two times in this data set the answer is 8 and 20 since it is the most common Answer: 8 and 20

Practice 2: 3, 3, 6, 4, 7, 14 Step 1: Arrange from Least to Greatest Least Greatest 3, 3, 4, 6, 7, 14 Step 2: Find the number that occurs the most often 3, 3, 4, 6, 7, 14 Since 3 appears two times in this data set the answer is 3 since it is the most common Answer: 3

Practice 3: 3, 11, 13, 11 Step 1: Arrange from Least to Greatest Least Greatest 3, 11, 11, 13 Step 2: Find the number that occurs the most often 3, 11, 11, 13 Since 11 appears three times in this data set the answer is 11 since the most common number Answer: 11
