Answers
MV= The variable that changes in the experiment ( either by nature- can change scientist- be changed or both )
RV= variable that could be impacted from the change (outcome)
CV= variable that stays the same
Why do scientists use controlled variables?
Scientists want to have as many variables stay the same except for the change (MV) for accurate and valid results.
