Question

1. For each of the following, identify the I.V. and D.V. and the nature of the I.V. (between or within groups). b. To determine if maze learning is affected by the type of maze used, 20 rats are randomly assigned to learn a standard alley maze (i.e., includes side walls; located on the lab floor); another 20 learn in an elevated maze (no side walls; raised above floor level). Learning is assumed to occur when the rats run through the maze without making any wrong turns. If the researchers were also interested in if size of reward (small or large) has an effect on learning, what type of factorial design could be used? Graph some potential results that show a main effect of each variable, but no interaction.

Explanation / Answer

Independent variable: Maze types: standard alley and elevated(manupulated, between) Dependent Variable : error source ( ratio) design: single-factor, 2-level, independent groups ndependent samplest-test
