    While keeping an aquarium of goldfish, you change brands of goldfish food. It seems to you that the goldfish are growing much more quickly with the new food. You want to test the effect of your new fish food on the rate of growth in the goldfish. The best design for a controlled experiment would be to divide your fish equally into two separate bowls and…

    • …feed them different amounts of the new food.

    • …feed them each the same amount of the new food.

    • … feed the fish in one bowl the old food, and the fish in the other bowl an equal amount of the new food.

    • …feed the fish in one bowl the old food. Feed the fish in the second bowl with half the amount of new food since you believe it is more nutritious.

    Correct Answer
    A. … feed the fish in one bowl the old food, and the fish in the other bowl an equal amount of the new food.
