Question

You are testing whether temperature has an effect on the breaking point of rubber bands. You take one rubber band and put it in the freezer and another is heated. A third rubber band is left at room temperature. The one left at room temperature is considered the control group. The ones that you froze and heated are considered the experimental group. You then test to see how many times you can stretch it before it breaks.
5. In the scenario above with the rubber bands, what are the dependent and independent variables?

Answer 1

Independent variable: Temperature 
Levels: Room temperature
Freezing point 0C
Boiling point 100C

Dependent variable: breaking point of rubber bands measured in certain amount of temperature
