\begin{array}{l}\begin{array} { r c r r r } 2006 & 2010 & \mathrm { D } & \mathrm { D } ^ { 2 } & \\hline 26 & 15 & 11 & 121 & \hat { S } _ { D } = 5.00 \22 & 23 & - 1 & 1 & S _ { \bar { D } } = 2.50 \17 & 14 & 3 & 9 & \15 & 10 & 5 & 25 & \ & & \Sigma = 18 & 156 &\end{array}\\begin{array} { l } t = \frac { 4.50 } { 2.50 } = 1.80 \t _ { .05 } ( 3 d f ) = 3.182 ext {; Retain } \mathrm { H } _ { 0 } \d = \frac { 4.50 } { 2.50 \sqrt { 4 } } = 0.90 \d = \frac { 1.80 } { \sqrt { 4 } } = 0.90 \\end{array}\end{array}

Conclusion: No significant shift in attitudes was demonstrated, although the effect size was large. It is difficult to demonstrate significant differences with small N's.
