Study Notes
Variables in Experiments
- Independent Variable: A factor that is manipulated in an experiment; its variation is not influenced by other variables.
- Dependent Variable: A factor that is measured in response to changes in the independent variable; its value depends on the manipulations made.
Experimental Design
- Control Group: The baseline group in studies that does not receive the treatment or intervention; used for comparison to evaluate the effect of the independent variable.
- Experimental Group: The group in a study that receives the treatment or intervention being tested; allows researchers to observe the effects of the independent variable.
Research Foundations
- Hypothesis: A testable prediction or educated guess based on limited evidence; serves as a starting point for scientific investigation and experimentation.
