CEM - Research - Technical Guide

I. Developing The Methodology

Applying a methodology appropriate to the question is a key to a successful project. The best research uses simple and standard methods. Complex methods may be required to answer complex questions - but only when the complex question cannot be broken down into a series of simple questions.

There are a number of areas that must be considered in developing the methodology:

Defining and refining your research question
Searching the literature
Project management and time management
Writing a research proposal
Sample size calculation
Sources of funding
Ethics, information and consent
Carrying out a pilot study
Bias and confounding
Validity and generalisability
Pragmatic versus explanatory trials
