In Chapter 7 we discussed a study on monitor size.In Chapter 11 we revisited this study and discovered it was actually a within subjects design.The research matrix is given below.
$$\begin{array} { | l | l | l | }
\hline 17 \text { inch } & 19 \text { inch } & 21 \text { inch } \
\hline 25 \text { participants } & 25 \text { participants } & 25 \text { participants } \
\hline
\end{array}$$
If you wanted to give every participant in the study a piece of paper with the contact information of the researchers, how many pieces of paper will you need for this within subjects design?

Since it is a within subjects design, each participant will only need to receive the contact information once. Therefore, the number of participants (25) is equal to the number of pieces of paper needed.
