1. Consider the following correlation coefficients presented below:

r = -.98            r= -.02             r= .85              r= .40                          r=.10

a. Which coefficient represents the greatest magnitude (strength)?

b. Which coefficient represents the least magnitude?

2. Using SPSS, analyze the data below:

                                                 Value of Automobile

 Own car alarms         $15,000 or less            $15,001-$29,999         $30,000 or more

 

Yes                              10                                30                                40

 

No                               20                                10                                10

Report and interpret your findings.  (if appropriate, report group means, p value, etc.)

3. Enter the following data into SPSS and calculate the correlation matrix for all four variables. Identify which correlations are significant and state and interpret your findings. Report significant correlation coefficients and p values.
