So what is it that they are trying to test?

Answer 5

this is what is says about it

Answer 6

Basically the control of a science experiment is that one thing that doesn't change for the sake of the experiment. In this case it's the fact that fluffy still ate what fluffy normally eats

Answer 7

So the experiment is to change what fluffy eats to test a theory, so the control would to be not changing anything

Answer 8

Sorry, rephrase?

the controlled variables are constant

Answer 12

Answer 13

Answer 14

Control groups actually help analize what works best; basically, it's staring out with a hypothesis.
A hypothesis is a basically guessing on how results will turn up to be without testing it just yet, so, a theory. In order to do an experiment, you have to start somewhere. Whereas Hagrid wanted to figure out what food works best for Fluffy since he wants/wanted to insert him into a dog competition.

So in summary:

Stating the hypotheses — Hagrid thinking Fluffy would lose weight with raw whole organic foods.

Formulating an analysis plan — Selecting 3 different diet plans.

Analyzing the sample data — Reviewing all 3 diets.

Analyzing the result — See which 1 worked out of the 3.
