* '''Experimental Design''' — The process of planning a study to meet specified objectives.
* '''Independent Variable (IV)''' — The factor that is manipulated by the researcher (the "cause").
* '''Dependent Variable (DV)''' — The factor that is measured (the "effect").
* '''Control Group''' — The group that does not receive the treatment, used as a baseline.
* '''Experimental Group''' — The group that receives the treatment.
* '''Randomization''' — Assigning participants to groups by chance to ensure the groups are similar at the start.
* '''Blinding''' — Keeping the participants (Single-blind) or both participants and researchers (Double-blind) unaware of who is in which group.
* '''Placebo''' — An inactive substance or treatment given to the control group.
* '''Sample Size (N)''' — The number of observations or participants in an experiment.
* '''Statistical Power''' — The probability that an experiment will detect an effect if one actually exists.
* '''Confounding Variable''' — An outside influence that changes the effect of a dependent and independent variable.
* '''Factorial Design''' — An experiment that studies the effect of two or more independent variables simultaneously.
* '''Replication''' — Repeating an experiment to see if the same results are achieved.
* '''Internal Validity''' — The degree to which the experiment shows a true cause-and-effect relationship.
* '''External Validity''' — The degree to which the results can be generalized to other settings or populations.
