please tell me if you agree with the following:
Which Brand of popcorn hs the least amount of unpooped kernels after 3 minutes.
Brand 1 has 1
Brand 2 has 15
Brand 3 has 16
Brand 4 has 5
Brand 5 has 25
the answer is Brand 1 BUT is the:
independent variable the different brands of popcorn?
is the dependent variable the un-popped popcorn?
is the constant the number of minutes?
What is the control?
You are right on with the variables.
I'm not sure what you mean by "the constant."
If you are comparing a treatment to a non-treatment, the non-treatment would be the control. Here you are comparing different brands, so no control is needed.
