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

A. Time six male mice and six female mice in the same maze; reward the male mice with fruit when they complete the maze, and reward the female mice with grains when they complete the maze.

B. Time six male mice and six female mice in the same maze; reward both male and female mice with fruit when they complete the maze.

C. Time six male mice in one maze and six female mice in a second similar maze; reward both male and female mice with cheese when they complete the maze.

D. Time each mouse in a different maze; reward the male mice with bread when they complete the maze, and reward the female mice with cheese when they complete the maze.

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.

Brisa Lawrence · Answer 2

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
