Write down 20 random numbers between Find the Mean, Median, and Mode of your data set you just wrote down.

It’s all about reppin’ your data

Goal To compare data sets using three different types of graphs.

Directions Each group will be given a data set (list of numbers) The data set will represent something from life. Bar graph Scatter Plot Box-whisker

Directions Each graph will have… The necessary parts labeled correctly The mean, median and mode pointed out Posters: Will be organized Have decorations that match the theme of the data set

Directions Presenting the posters: Two days from today Each person must participate Each graph must be explained Explain how each graphs shows the mean, median and mode of the data set

Sample: Mean 6, 17, 24, 35, 3, 5, 36, 42, 13, 6 The mean you know how to find. Add up and divide by the quantity of the data set =

Median 3, 5, 6, 6, 13, 17, 24, 35, 36, 42 Median – What is the middle number The middle is “13, 17” …what now? If it is two numbers you add and divide by two. = 15

Mode 3, 5, 6, 6, 13, 17, 24, 35, 36, 42 The data that occurs the most frequently What is this one? Mode = 6

Box and Whisker 5 things you need to find to make a box and whisker Median “Q2” Median of lower half of data “Q1” Median of upper half of data “Q3” Lowest number in data Highest number in data

LowestHighest Q1Q2Q3 Lower half median Median Upper half median

Bar graph Leave the numbers in the order you were given them!!!! Do not rearrange them least to greatest.

Scatter Plot Leave the numbers in the order you were given them!!!! Do not rearrange them least to greatest.

Breaking up into Groups I will assign the groups No you cannot change groups. Your job Make a poster showing your data with 3 different graphs, all labeled correctly Two days from today you will present your posters to the class
