Quantitative research can be defined as a type of research that explains phenomena by collecting numerical data that are analyzed using mathematically based methods (in particular statistics) (Creswell, 1994).
On the following pages you will find examples of studies done using quantitative research methods. These methods are broken down into three sections; Experimental, Quasi-experimental and Survey. Each page provides a summary of the study.
