Paul was interested in how associated a whole set of 7 quiz items was. He calculated the median lors for each of the quiz items with each question removed. The results are shown below:
$$\begin{array} { | l | l | l | l | l | l | l | }
\hline ? & \text { w/o } & \text { w/o } & \text { w/o } & \text { w/o } & \text { w/o } & \text { w/o } \
& \mathrm { Q } 2 & \mathrm { Q } 3 & \mathrm { Q } 4 & \mathrm { Q } 5 & \text { Q6 } & \text { Q7 } \
\hline 0.87 & 0.79 & 1.35 & 0.95 & 0.68 & 0.81 & 0.51 \
\hline
\end{array}$$ On the basis of the results, which question (if any) may Janet wish to remove from her data?
A) Question 5
B) Question 7
C) Question 3
D) None

The median lors (log odds ratios) for each question with one question removed show how associated each question is with the overall quiz. The higher the median lor, the more associated the question is. Question 3 has the highest median lor (1.35) when it is removed, indicating that its removal increases the association among the remaining questions the most. Therefore, Janet may wish to remove Question 3 to improve the overall association among the quiz items.
