SPSS Handout: Repeat the work of page 1, and do problems 1-5 on p. 3.  Keep this work and hand it all in when all problems have been assigned. 

HW in Activstats:  Go to Chapter 7, use the menu button with the House icon.  Scroll thru the problem list to find the ones given.  In each problem involving data, a button will allow you to launch SPSS and open the correct file.  Then save the file for yourself, do the analysis.
MRA-81-4 (SPSS) Metabolic Rates, M/F
MRA-83-8 (SPSS) Ed. Spending vs. Teacher Salaries 
MRA-80-2 (SPSS)  Speed vs. Fuel Consumption (describe)
TRE-58-26 (SPSS)  Bear neck/weight  ALSO Make a plot with the M&F bears marked differently.  What if any sex differences do you see here?

MRA-95-13 (SPSS, and pencil) Corn plants.  This is a first introduction to the idea of predicting or estimating a "typical" y for a given x value.  Ch. 8 will do an important special case of that.

Correlation (beginning): 
SPSS Handout: Do problem 6, p. 3.  Keep this with the previous work.
p. 130 #11, 12  Match # to scatter.  (Use handout of typical ones, AS7-3 Activity 2)
ActivStats: MRA-89-4 (SPSS) Speed vs. Fuel Consumption (cf. MRA-80-2) r~0, why?
+ + + + + + + + + + +
Postpone: Correlation: (more)
p.130, 13 lunchtime (SPSS)
  16 Drug abuse (SPSS)
   26 Oil consumption (SPSS) (this is another timeplot)
   23 Correlation errors
A.  If women always married men who were two years older than themselves, what would be the correlation between the ages of husband and wife? (Hint: make  a data table and the corresponding scatterplot for 4-5 couples with different x's)
Your click-in-the-Circle Data:
ActivStats(Ch.8)HW  ACT-2 Circle Correlations. (SPSS) (copied here) What is the association between the time it took you to click in a circle and the size of the circle?  Does it typically take longer to click in a smaller circle?
What is the association between the time it took you to click in a circle and the distance you had to move to reach the circle?
What is the association between the distance of your click from the center of the circle and the size of the circle?  Can you account for the pattern you see?
Write a paragraph summarizing these relationships.
(If you forgot to make scatterplots before computing correlations, you might want to go back and make them now, before anyone notices.  Be sure to discuss any unusual patterns or points you see in the scatterplot and note how they might have affected the correlations you computed.)Don't forget to do scatterplots as well as computing correlations. Cf. Circle questions

to make different scatterplot 
patterns, and observe their r's.

If you feel at all shaky about
graphing or using straight lines
(slopes, intercepts) be sure to
do Linear Equations exercise
 and Line Equations,
