    AbstractThis fourth article of a series of six focuses on some of the key aspects of quantitative research methods. Starting with a review of what quantitative research is, the distinguishing characteristics of experimental and non-experimental research strategies, the different approaches for collecting data including self-completion questionnaires, interviews and scales, together with their respective strength and weaknesses are discussed. The differences between probability and non-probability sampling and the different methods for selecting a sample are described. Aspects of quantitative data analysis are briefly reviewed and the concepts of reliability and validity are described in the context of ensuring rigour in the research design. Finally, some guidance on the reporting the findings from quantitative research is provided.
