You plan to compare two different diets that are used to feed tadpoles raised in a lab. One diet is meat-based fish food. The other diet is the traditional diet of boiled lettuce. You want to know if the meat-based diet will be associated with an increase in the average overall weight of the tadpoles. In the experiment you keep all other factors such as temperature, pH, tadpole density per pan, and amount of food constant (controlled variables). The only thing that is different is the type of food between the two groups. Based on the information provided, what is the dependent variable?
