Suppose you want to find out which dog food your dog likes best. write about the experiment you would design. what variables do you need to control? how would you avoid experimental bias? write a scientific hypothesis.

answer all these questions.

By giving the dog 2 or more different dog foods and seeing what one he eats the must of and the variables u control is how much you give the dog and the hypothesis is if I give the dog two or more different kinds of dog food than we will see what one he/she like the most

Ithink it’s 3 as the answer.
