Quantitative research

Quantitative research uses the scientific method to construct knowledge through operationalisation of variables and utilising statistical procedures to analyse numerical data (Breen & Darlaston-Jones, 2010) such as collected via self-report scales, behavioural measures, or physiological measures.

Quantitative research is based on the epistemology of positivism, which assumes that reality is objective, singular, and governed by universal laws. The discovery of these laws is the overarching aim of quantitative research, with the goal of describing, explaining, predicting, and controlling phenomenon (Breen & Darlaston-Jones, 2010).

Quantitative research utilises an objective, deductive methodology characterised by structured procedures that collect reliable numerical measurement.
