Experimental Design:Experimental design refers to the specific plan or blueprint that researchers create in order to test their hypotheses. It outlines how participants will be assigned to different conditions, what variables will be manipulated, and how data will be collected.
Quasi-Experimental Design: Quasi-experimental design is similar to experimental design but lacks full control over certain variables due to ethical or practical reasons. Researchers still manipulate independent variables but cannot randomly assign participants.
Correlational Study:A correlational study investigates the relationship between two or more variables without manipulating any factors. It aims to determine whether changes in one variable are associated with changes in another variable.
