A descriptive correlational design is a quantitative research design. A confounding variable is a third variable that influences other variables to make them seem causally related even though they are not. All descriptive correlational method studies have the same basic property of avoiding any direct changes in the environment of the study. << Correlational research is a type of non-experimental research method in which a researcher measures two variables, understands and assesses the statistical relationship between them with no influence from any extraneous variable. Correlational designs involve the systematic investigation of the nature of relationships, or associations between and among variables, rather than direct cause-effect relationships. 1 0 obj Although a correlational study cant demonstrate causation on its own, it can help you develop a causal hypothesis thats tested in controlled experiments.
