Independent variable is the condition that is changed in an experiment. Dependent variable is the condition that is measured in an experiment. Independent variable is controlled by the experimenter. Dependent variable depends on the independent variable
Control group receives no experimental treatment, while experimental group receives manipulation. Control group serves as baseline for comparing experimental group changes. Both groups are identical except for experimental manipulation. Participants are randomly assigned to either group
Experimental research manipulates independent variables to measure their effects on dependent variables. Widely used in physical, social sciences, psychology, and education. Based on comparison between groups with straightforward logic
Control group consists of participants who don't receive experimental treatment. Participants are randomly assigned to control group. Control group serves as baseline for comparing experimental results
Variables are categories or characteristics measured in equations or experiments. Independent variables stand alone and aren't affected by others. Dependent variables are effects or results that depend on other factors
Experimental method manipulates variables to determine cause-and-effect relationships. Researchers randomly assign participants to control or experimental groups. Independent variable is manipulated, dependent variable is measured. Scientific method and positivism form basis of experimental approach
