Experimental Research Design

Experimental research design is a method used by researchers to investigate cause-and-effect relationships. It involves planning a study where participants are divided into groups—typically an experimental group receiving a specific treatment and a control group that does not. The researcher then applies the treatment to see if it produces changes, allowing for comparison between groups. This design helps determine whether observed effects are due to the treatment itself, rather than other factors, and ensures the study's findings are reliable and valid.
