META ANALYSIS

STA5MA

2018

Credit points: 15

Subject outline

The literature abounds with findings that collectively may offer important new insights for the betterment of the medical, psychological and life sciences, to name just a few.  This subject is designed to provide students with the ability to combine estimated measures of evidence, known as effects, from comparable studies to increase power.  Estimators are introduced which are commonly found in meta-analytic research and pitfalls are discussed.  On completion of the subject, the student will have an understanding of the different effects that can be collected from the literature as well as an appreciation of how effect sizes arising from data measured on different scales can be combined. Importantly, this subject also shows students how meta-regression can be used to account for study-specific covariates that cannot be adequately accounted for using random-effects models.  The freely available software packages R and RevMan are used throughout the subject.

Graduate capabilities & intended learning outcomes

01. Present clear, well-structured arguments that validate the combination of effect sizes from several studies that may differ in several aspects, including with respect to moderators and data measurement scales.

04. Critique and summarise published meta-analyses, clearly highlighting weaknesses and flaws that undermine the key findings.

Activities:
Modeled via example in online lectures and readings. In some computer laboratory classes, students will be required to highlight problems with published findings and re-analyse the data correct to observe differences. This is under the guidance of the demonstrator.
