Study Notes
Independent Variables
- Independent variables are manipulated or changed by researchers in an experiment to observe effects on dependent variables.
- In an experiment testing vitamins for life expectancy, the independent variable is the dosage of the vitamin administered to participants.
- Administration of a drug in a cancer study is another example of an independent variable.
Dependent Variables
- Dependent variables are outcomes measured in an experiment that are influenced by changes in independent variables.
- For the vitamin life expectancy experiment, the dependent variable is the resulting life span of the subjects.
- In the cancer drug study, the dependent variable is the effect of the drug on the progression of cancer.
