Experimental Research
Experimental research uses manipulation and controlled testing to understand causal relationships between variables. It involves manipulating one or more independent variables and observing their effect on a dependent variable. There are three main types of experimental designs: pre-experimental, true experimental, and quasi-experimental. True experiments have control groups, random assignment, and manipulation of a single independent variable. Quasi-experiments lack random assignment. Experimental research is commonly used in fields like psychology, medicine, and social sciences to establish causal relationships.
