Two's Day HW

Tonight, please complete the following:

1.) Count up your stamps and have them ready to turn in at the start of class tomorrow (instructions below).

2.) STUDY! Tomorrow = chapter 8 vocab quiz (list below)

STAMPS ARE DUE WEDNESDAY!

• Gather all your stamps--you can leave them on the full paper, or rip off the little stamp, whatever is easier
• You will get all of these back, so if you have notes on a paper with a stamp, don't worry, you'll get it back
• If you count your stamps in class you will be given a zero--this is your responsibility OUTSIDE the classroom
• Count all your stamps--double check!
• I will choose 5 random names from each class and double check those students' stamps; if your total is incorrect, you will earn a score of 0
• Fasten all your stamps--put them in a ziploc bag, put them in an envelope, staple them all together, or maybe glue/tape all the cut out stamps to one paper--whatever works best for you
• Write your name and the total on the front of your stamps
• Turn this in by Wednesday!
• Stamps count as a classwork grade!
• For each class I will find Q3 and use this to determine how many points the stamp grade is out of, so I can't tell you how many you need....
• It doesn't really matter how many you need anyway, you just have to turn in all your stamps!

Chapter 8 Vocab Quiz Wednesday!

• Residual (what does it measure? how is it calculated? how is it represented visually on a scaterplot?)
• Actual Value (y): based on given data or the point in a scatterplot
• Predicted Value (y-hat): generated by substituting into the LSRL equation or looking at the line of best fit
• Interpret Slope
• Interpret Y Intercept
• Coefficient of Determination = R^2
• Interpret R^2
• Correlation
• Underestimate (connect to residuals)
• Overestimate (connect to residuals)
• Linear Model
• Least Squares Regression Line (LSRL)
• "Is a linear model appropriate?" (what do we check?)
• Explanatory Variable
• Response Variable
• Scatter plot
• Lurking Variable

Today's Class Recap:

• Quiz! (Interpret slope, intercept, r, r-squared)
