Experimental Research Questions
The role of random assignment in minimizing selection bias in experimental research is to ensure that participants are assigned to different groups or conditions in a completely random manner. This helps to eliminate any systematic differences between the groups, such as individual characteristics or preferences, that could potentially influence the outcome of the study. By randomly assigning participants, researchers can be more confident that any observed differences between the groups are due to the treatment or intervention being studied, rather than pre-existing differences among the participants. Random assignment helps to create comparable groups, reducing the likelihood of selection bias and increasing the internal validity of the research.
