This criterion assesses the extent to which the student has developed an appropriate and repeatable method to collect data that is relevant to the research question. The data could be primary or secondary, qualitative or quantitative. A method that is repeatable should include sufficient details to allow a third party to replicate the investigation.
The description of the method should include the set-up and the student contribution, sampling or surveying techniques, and how data is collected. A descriptive, literature-based investigation that only reviews the literature cannot be considered a repeatable method.
