Question

What is the Independent Variable and Dependent Variable?. What brand of soda contains the most caffeine.

​

Answer 1

An independent variable is a variable that is changed only by the experimenter. A dependent variable however is the variable being tested and being changed by the independent variable. For example, if you're doing an experiment on what would happen if you gave a plant 1 liter of water everyday to a plant, the independent variable would be the water as it was changed on by the experimenter. And the dependent variable would be the plant since it is the one being experimented on and the one being affected by the independent variable.

I assume the next question is missing context but just in case, it would be the Pepsi One, but it’s discounted so it would be a Mountain Dew.

Answer 2

an independent variable is a variable that does not rely on the other. a dependent variable depends on the independent variable to change. as you change the independent, the dependent variable changes. also I believe pepsi or coke has the most caffeine
