Question 3

$\begin{array}{lcc}
\hline \text { Source } & F & p \
\hline \begin{array}{l}
\text { Grade level \{elementary, } \
\text { middle, high\} }
\end{array} & 15.31 & .042 \
\text { SES (low, middle high\} } & 3.96 &.194 \
\begin{array}{l}
\text { Interaction \{Grades } \times \
\text { SES\} }
