A comparative psychologist was interested in the effect of X-irradiation on learning. A group of rats learned a simple maze and were paired on the basis of the number of errors. One group was X?irradiated; then both groups learned a new, more complicated maze, and errors were recorded.
a. Test for a difference between the two groups. Find the effect size index. Write a conclusion for the study. $$\begin{array} { c c }
\text { X-irradiated } & \text { Control } \
\hline 14 & 12 \
12 & 10 \
8 & 11 \
15 & 13 \
17 & 12
\end{array}$$
b. Identify the independent and dependent variables.
