Variable $=$ Grade point average


$\begin{array} { l c c c c } \text { GROUP } & N & \text { Mean } & S D & \text { Standard Error } \\ \text { GROUP 1 } & 15 & 2.95 & 0.556 & 0.143 \\ \text { GROUP 2 } & 15 & 3.08 & 0.524 & 0.135 \end{array}$


$F _ { \max }$ test $\quad F = 0.225 \quad p = 0.639$
Equal Variances Assumed
$t = - 0.68 \quad d f = 28 \quad p = 0.509$
Equal Variances Not Assumed
$t = - 0.68 \quad d f = 27.90 \quad p = 0.509$
-Consult Table 10-1. The data indicate ________ of variance; therefore, we should use the output under _________________.
