Section Introduction:

Quantitative research uses the scientific method to evaluate theories or problems by testing specific hypotheses involving the relationship among or the differences between variables.  The variables are measured using numerical data, allowing statistical procedures to be used for a mathematical analysis.  Many different quantitative designs exist within a basic or applied context to accurately address the purpose of the research and related research questions.

Non-Experimental (Non-Causal) Correlational Designs
A correlational design is one of the most often encountered non-experimental (non-causal) quantitative designs.  Within correlational designs, an actual experimental condition is non-existent; rather, relationships between variables are explored without a determination of causality.  These types of studies are meant to help researchers examine how two or more variables vary in
