Question

a b c total d 0.12 0.78 0.10 1.0 e r s t 1.0 total u x y 1.0 which value for r in the table would most likely indicate an association between the conditional variables? 0.09 0.10 0.13 0.79

Explanation:

Step1: Find independent case value for R

If variables are independent, $R = U \times 1.0$, and $U = 0.12$ (total for column A from row D total). So independent $R=0.12$.

Step2: Identify value farthest from 0.12

Compare options: $|0.09-0.12|=0.03$, $|0.10-0.12|=0.02$, $|0.13-0.12|=0.01$, $|0.79-0.12|=0.67$. The largest difference is 0.67 for 0.79.

Step3: Link difference to association

A large difference from the independent value indicates association.

Answer:

0.79
