Short Answer

Questions below are based on the following: (This is similar to an item in the text at the back of chapter 12 but WITH A DIFFERENT DATA SET). A researcher is interested in whether a certain amphetamine drug will affect the retention of learned behavior among rats as a function of how much time is allowed to elapse between the training and the retention test. Four groups, ten subjects in each group, were randomly selected from a colony of Sprague-Dawley rats. All the rats were given the same amount of training on a simple maze. Groups A and C were given the amphetamine, whereas Groups B and D were given a placebo. Groups A and B were tested for retention immediately following the training, whereas Groups C and D were tested 4 hours later. The retention measure consisted of a scaled score based on how many correct responses the rats would exhibit while running the maze, the higher the score the higher the retention $$\begin{array}{l}\quad\quad\quad\quad\quad\quad\quad\quad\quad\quad\text { FACTOR A }\\\begin{array} { l c c } & \begin{array} { c c } \text { Amphetamine } \\\text { Group A }\end{array} & \begin{array} { c } \text { Placebo } \\\text { Group B }\end{array} \\& 15 & 13 \\& 9 & 9 \\& 9 & 12 \\\text { Immediate } & 11 & 7 \\\text { Test } & 10 & 7 \\& 6 & 8 \\& 10 & 10 \\& 12 & 9 \\& 14 & 5 \\& 7 & 11 \\& \text { FACTOR B } & \\& \text { Group C } & \text { Group D } \\& 1 & 8 \\& 5 & 6 \\\text { Delayed } & 2 & 9 \\\text { Test } & 4 & 4 \\& 5 & 4 \\& 6 & 5 \\& 5 & 6 \\& 2 & 6 \\& 6 & 6 \\& 1 & 7\end{array}\end{array}$$
