At the Seymour Clinic, the number of patients seen by three doctors over five days is as follows: $$\begin{array}{l}\quad\quad\quad\quad\quad\quad\quad\quad\text { Physician }\\\begin{array} { | c | c | c | c |} \hline { \text { Day } } & { \text { Dr. Able } } & { \text { Dr. Baker } } & \text { Dr. Chow } \\\hline \text { Mon } & 19 & 25 & 27 \\\hline \text { Tue } & 20 & 22 & 27 \\\hline \text { Wed } & 22 & 24 & 32 \\\hline \text { Thu } & 19 & 20 & 22 \\\hline \text { Fri } & 20 & 34 & 27 \\\hline\end{array}\end{array}$$ This data set would call for:
