Learning Outcomes

The aim of this paper is to provide students with the knowledge and skills to translate a research aim into specific study objectives, construct a study design to address the objective(s), and write a plan for the statistical analysis.

Specifically, on completion of this paper students will be able to:

  1. Distinguish different types of studies and identify appropriate designs for addressing different types of research questions.
  2. Describe the roles of confounders, mediators and effect modifiers in a study design and analysis and determine an appropriate estimand to address the research question.
  3. Identify the relevant sources of variation and correlation and the units of replication.
  4. Identify potential sources of bias in a study and design a study to minimise bias.
  5. Design and plan the analysis for:
    1. a complex survey.
    2. an experiment.
    3. an observational study.
  6. Carry out a statistical evaluation of a study design, including power and sample size determination.
  7. Describe the ethical considerations in the design, conduct, analysis and reporting of a research study.
