Experimental studies The research questions for this study were: 1. %���� In this design, a set of experimental units is grouped (blocked) in a way that minimizes the variability among the units within groups (blocks). An experimental research design is a research design that helps in measuring the influence of the independent variable on the dependent variable. Control over treatment: The researcher usually designs the treatment and decides which subjects receive it. The following questions address a number of key design features that must be considered. 2.
