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?

• Statistics -

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.
