Experimental Group #
An experimental group is a group of participants in an experimental study that receives a specific treatment, intervention, or manipulation of the independent variable. Researchers compare the outcomes of the experimental group with those of a control group to assess the effects of the treatment.
Control Group #
A control group is a group of participants in an experimental study that does not receive the treatment or manipulation of the independent variable. Control groups provide a baseline for comparison with the experimental group and help researchers evaluate the effects of the treatment.
Random Assignment #
Random assignment is a technique used in experimental research to assign participants to different groups (experimental and control) randomly, ensuring that each participant has an equal chance of being in either group. This method helps minimize bias and ensure the internal validity of the study.
Independent Variable #
An independent variable is a factor or condition that is manipulated or controlled by the researcher to observe its effects on the dependent variable. In experimental studies, the independent variable is hypothesized to cause changes in the dependent variable.
Dependent Variable #
A dependent variable is a factor or outcome that is measured or observed to assess the effects of the independent variable in a research study. Changes in the dependent variable are expected to result from the manipulation or treatment of the independent variable.
Control Variable #
A control variable is a factor that is held constant or standardized in a research study to prevent its influence on the relationship between the independent and dependent variables. Controlling for extraneous variables helps researchers isolate the effects of the independent variable.
Mediating Variable #
A mediating variable is an intermediary factor that explains the relationship between the independent and dependent variables in a research study. This variable helps researchers understand the underlying mechanisms or processes through which the independent variable influences the dependent variable.
Moderating Variable #
A moderating variable is a factor that influences the strength or direction of the relationship between the independent and dependent variables in a research study. Moderating variables help researchers identify conditions under which the relationship between variables may vary.
Validity Threats #
Validity threats are factors or errors that may compromise the internal or external validity of a research study, leading to biased or inaccurate results. Researchers must be aware of validity threats and take steps to minimize their impact on the validity of their findings.
Reliability Threats #
Reliability threats are factors or errors that may affect the consistency and stability of research findings, leading to unreliable or inconsistent results. Researchers must address reliability threats and ensure the dependability of their data and analyses.
Triangulation #
Triangulation is a methodological approach that involves using multiple sources of data, methods, or researchers to corroborate findings, enhance validity, and reduce bias in a research study. By triangulating data, researchers can strengthen the credibility and reliability of their results.
Research Paradigm #
