Question
A scientist carries out an experiment to determine if a new weight control drug will make mice lose weight. What is the independent variable?
Solution
The independent variable in this experiment is the new weight control drug. This is because the scientist is manipulating the use of this drug to see its effect on the weight of the mice. The independent variable is the factor that is changed or controlled in a scientific experiment to test the effects on the dependent variable, which in this case is the weight of the mice.
