Question

Choose the best experimental design to test the question “Does the gender of mice affect the time it takes to learn mazes?”

Answer 1

In making an experiment their are two types of variable that should be consider, one is the dependent variable and the other one is the independent variables. I the question that dependent variable would be the result or the effect of the gender of mice and the independent is the ways in determining it. So the variables should be fair if you want your result to have no bias. Thus the answer would be letter B. because it has the same variables but different in gender 

Answer 2

I believe the answer to be B, because they are doing the same maze, and getting the same rewards for completing the maze, so it's fair.
