Characteristics of the Three Research DesignsResearch designGoalAdvantagesDisadvantages
DescriptiveTo create a snapshot of the current state of affairsProvides a relatively complete picture of what is occurring at a given time. Allows the development of questions for further study.Does not assess relationships among variables. May be unethical if participants do not know they are being observed.CorrelationalTo assess the relationships between and among two or more variablesAllows testing of expected relationships between and among variables and the making of predictions. Can assess these relationships in everyday life events.Cannot be used to draw inferences about the causal relationships between and among the variables.ExperimentalTo assess the causal impact of one or more experimental manipulations on a dependent variableAllows drawing of conclusions about the causal relationships among variables.Cannot experimentally manipulate many important variables. May be expensive and time consuming.
