Introduction[edit | edit source]
Quantitative research is a type of research that assumes that the phenomena under study can be measured and involves methods that:
- gather data using measurement (numerical data)
- analyse data by using quantitative statistical analysis techniques.
Designs in quantitative research[edit | edit source]
There are two main types of quantitative research designs: [1]
- Survey
- Experimental
Survey research designs[edit | edit source]

Experimental research designs[edit | edit source]
In experimental research designs, the researcher can manipulate one (or more) variable(s), the independent variable, and study the effect on a dependent variable. [1] There are many types of experimental designs; one of the most important is the randomised controlled trial.
Randomised controlled trials[edit | edit source]
Randomised controlled trials are considered top methods in the hierarchy of evidence when testing the link between cause and effect in clinical interventions. [2][3]
