Purpose of the Unit: Think about the Warm-Up Purpose of the warm-up:Many of the persuasive choices you make in English can be made in presenting math as well Purpose of the unit: This unit will help you to think logically about the information you are presented with, determine if it is a fair picture of the data, and create your own statistics from questions you create. *DO NOT click "next" until you have completed all notes and activities for this page!*

Where are we going in this unit? Day 1: Overview (today) Day 2: Misleading Data Day 3: Reading Scatter Plots Day 4: Creating Scatter Plots Day 5: Solve for the Equation of a Trend Line Day 6: Solve for the Equation of a Trend Line and Judge Fit Day 7: Predict Future Values from Scatter Plots Review Test: May 2nd *DO NOT click "next" until you have completed all notes and activities for this page!*

Overview Day: Master the Basics SWBAT form excellent quantitative questions SWBAT choose appropriate scales for graphs SWBAT identify independent and dependent variables *DO NOT click "next" until you have completed all notes and activities for this page!*

Vocab Reminder Qualitative: Data that deals with qualities Example: Color of your hair Quantative:Data that deals with numbers Example: Size shoes you wear Correlation: Data that “goes together”. One affects the other, or they move together. *DO NOT click "next" until you have completed all notes and activities for this page!*

For this unit, we need 2 sets of data that are correlated Let’s think of questions that “go together”, or questions where the data will be related, like – What is your shoe size and your height? – How much did you study and what was your recent test score? – How much TV do you watch and what is your average homework percentage? List 2 more in your notes *DO NOT click "next" until you have completed all notes and activities for this page!*

Quantitative Questions For this unit we are going to focus on quantitative question sets only because they are easier to graph since they use numbers. Brainstorm 3 quantitative questions (must be different from before) *DO NOT click "next" until you have completed all notes and activities for this page!*

Independent vs. Dependent Independent: Data that is not affected by anything else. It is the variable being changed. X-values. Dependent: Data that is being measured. It DEPENDS on the independent data. Y-values. Example: Grade on exit ticket and test score independent dependent *DO NOT click "next" until you have completed all notes and activities for this page!*

Independent vs. Dependent Go back to your list of qualitative questions and label one as the “independent” and the other as the “dependent” variable. *DO NOT click "next" until you have completed all notes and activities for this page!*

Selecting A Scale Before you can avoid things like exaggeration in English class, commercials or ads, you need to know a little bit about your subject. Same with math. Before you can avoid being tricked by misleading data, you need to understand how to represent data appropriately *DO NOT click "next" until you have completed all notes and activities for this page!*

Selecting A Scale Height60”54”67”48”50”52” Weight135 lbs120 lbs190 lbs110 lbs109 lbs100 lbs Directions: Look at the table below. What is the independent variable? The dependent variable? What is the lowest value of the independent variable? What is the highest value of the independent variable? What is the lowest value of the dependent variable? What is the highest value of the dependent variable? *DO NOT click "next" until you have completed all notes and activities for this page!*

Selecting A Scale When you select your scale, you are going to use these same steps. 1.Identify the lowest value of your independent variable. This is the low value of your x-axis 2.Identify the highest value of your independent variable. This is the highest value of your x-axis 3.Identify the lowest value of your dependent variable. This is the low value of your y-axis. 4.Identify the highest value of your dependent variable. This is the highest value of your y-axis. THEN 5. Choose an amount to move by so your graph doesn’t take too much or too little space. *DO NOT click "next" until you have completed all notes and activities for this page!*

Selecting a Scale Independent: Height—lowest: 50, highest: 67 Dependent: Weight—lowest: 100, highest: 190 Weight: Moving by 50’s made sense for the y-axis Height: Moving by 20’s made sense for the y-axis *DO NOT click "next" until you have completed all notes and activities for this page!*

Selecting a Scale Select the appropriate scale for the graph below by following the steps listed on the previous page. Graph the data on your graph. Number of cats Number of mice *DO NOT click "next" until you have completed all notes and activities for this page!*

Think you got it? Make sure you can: SWBAT form excellent quantitative questions SWBAT choose appropriate scales for graphs SWBAT identify independent and dependent variables Be able to define: Correlation, qualitative, quantitative, independent, dependent *DO NOT click "next" until you have completed all notes and activities for this page!*
