Tuesday/Wednesday

Your homework is....STUDY! Be ready for your chapter 7 quiz (vocab and math) Thursday!

For Tuesday, get a good night's sleep and come ready to put forth your best effort on Wednesday for the SAT or PSAT!

Here's an outline of what you need to know for the open-ended/math portion of the quiz:

• Create a scatterplot and calculate r using your graphing calculator
• Describe the association seen in the scatterplot
• Find the mistakes in two statements about correlation
• Identify a potential lurking variable for a scenario
• Use the homework problems from last night to study! 
• Page 160-167: 5, 11, 13, 19, 25, 29
• These problems review everything that's on the quiz! So try them and be sure to check your answers in the back of the book!

And here's the vocab list for the chapter 7 vocab quiz!

• Scatterplot
• Explanatory Variable
• Response Variable
• Lurking Variable
• Correlation (r)
• Positive Association
• Negative Association
• Describe an association: we comment on shape, direction, and strength
• Outlier: a data point that falls outside the general pattern in a scatterplot
• Is a linear model appropriate: check for outliers, quantitative variables, roughly linear scatterplot

See you tomorrow (or Thursday)! Enjoy your afternoon and this little blast of summer weather!
