There are three main types of research design: exploratory, descriptive, and causal. Exploratory research is used to gain background information, define terms, and clarify problems and hypotheses. Descriptive research describes and measures phenomena at a point in time using cross-sectional or longitudinal studies. Causal research determines causality using experiments that manipulate independent variables to see their effect on dependent variables while controlling for extraneous variables. The choice of design depends on research objectives and what is known about the problem.
