A research design is a blueprint for conducting a study. Non-experimental (correlational) research is lowest in internal validity because these designs fail to use manipulation or control. Over the years, several quantitative designs have been developed for conducting descriptive, correlational, quasi-experimental, and experimental studies. In most of cases, correlational research includes at least two measurements according to each the variables should be examined. In our previous article in this series,[] we introduced the concept of "study designs"- as "the set of methods and procedures used to collect and analyze data on variables specified in a particular research question."Study designs are primarily of two types - observational and interventional, with the former being loosely divided into "descriptive" and .

A descriptive correlational study is a study in which the researcher is primarily interested in describing relationships among variables, without seeking to establish a causal connection.
