In an experiment, the researcher is looking for the possible effect on the dependent variable that might be caused by changing the independent . In the tadpole diet experiment, it would be sufficient to test only one single pan of tadpoles that were fed lettuce, and only one single pan of tadpoles fed meat. Identify independent variables: Imagine that you wish to compare the two different diets that will be fed to tadpoles raised in a lab. You want to see if the meat-based diet will be associated with an increase in the average weight of the tadpoles. You want to decide if the new diet will be associated with an increase in the average weight of the tadpoles. -Diet will have no effect on tadpole size. Write an alternate hypothesis for this experiment: Based on the null hypothesis, I hypothesize that there will in fact be either an increase or decrease in the tadpoles weight base on their diets in a controlled experiment. Biology. The independent variable is what you change, and the dependent variable is what happens because of the change. The tadpoles weight will neither increase nor decrease based on the type of food they receive . Independent variables are what we expect will influence dependent variables. 1 Answer.
