Question: This set of questions pertains to variables Z and W (use the computational formula in Cohen et al.)

1. Given the measurement scales for variables Z and W, provide a variable name for each;
2. State the null and alternative statistical hypotheses for the relationship (based on 3a).
3. Construct a summary table for variables Z and W.
4. What is the correlation between Z and W?

   (fo-fe)^2/fe
   0.1	0.1
   0.1	0.1

   
   which means that the Chi-Square statistics is 0.1+0.1+0.1+0.1 = 0.4. Then, the correlation is
   \[\phi =\sqrt{\frac{0.41}{10}}=0.202485\]
5. Write a brief statement summarizing the results from 3d.
6. Are the data consistent with your hypothesis (3b)?
