Question

You have conducted an experiment examining the effect of a high fat diet on weight gain in hamsters. You feed 20 hamsters a high fat diet, 20 hamsters receive a low fat diet and 20 hamsters receive a fat free diet. At the end of 3 weeks, you weigh each hamster and calculate the average weight gain. You then graph the data. What do you put on the X axis?

The diet groups for the hamsters (high fat, low fat, no fat)

Average weight gain

Average total weight of the hamsters at 3 weeks

Each individual hamster's final weight

The diet groups for the hamsters (high fat, low fat, no fat)

Average weight gain

Average total weight of the hamsters at 3 weeks

Each individual hamster's final weight

Explanation / Answer
