Answer
a) If there is a reward, the mice will learn to complete the maze faster.
b) The control group is the mice with no reward and the experimental group is the mice with the reward. A control group is necessary for comparison.
c) Some variables that must be controlled include the length of the maze and the condition of the mice.
d) The data does support the hypothesis because it shows that mice with the reward took less time to complete the maze over time compared to the mice with no reward.
Work Step by Step
a) Look at the dependent and independent variables.
b) Identify what is the difference between the different groups in the experiment. In this case, it is a reward versus no reward.
c) Anything that is not being tested should be the same.
d) Look at the graph.
