The accurate statements about independent and dependent variables are:
- Both the independent and dependent variables are mentioned in the hypothesis.
- Experiments test for a relationship between the independent and dependent variable.
- The independent variable is manipulated by the scientist.
The following statements are not accurate:
- The dependent variable will never change during the experiment. (This is inaccurate because the dependent variable is expected to change in response to the manipulation of the independent variable.)
- The independent variables are held constant during an experiment. (This statement is misleading; while the independent variable is intentionally manipulated, other variables typically need to be controlled or held constant to ensure a fair test.)
