    Overview

    Design of studies to address different types of research questions. Survey methods, experimental and observational studies, measurement, control of confounding and bias, evaluation of competing designs, determination of study size.

    The reliability of the findings from a research study depends critically on the design of the study. An understanding of the principles of study design is important for all consumers of scientific research, and essential for all those who will be carrying out scientific research. 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. Students will also learn skills in critical evaluation of published research papers.

    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.
