Course Objective

Meta analysis is used for statistically combining information from various studies. It provides researchers with tools that allow them to statistically synthesize the different findings into a single statistical outcome. Also, it allows the researchers to assess the dispersion of effects and distinguish between real dispersion and spurious dispersion which as a result can put light on hidden effects taking part in a particular result that could not be seen in a single study. In this course, the students will learn the steps involved in conducting a meta analysis, commonly used effect sizes and their sampling distributions, converting effect sizes, fixed effect and random effects meta analysis models, heterogeneity, subgroup analysis, meta-regression, power analysis for meta analysis and publication bias. R programming language will be used for applications throughout the course.

Learning Outcomes of the Course Unit

1   Choose appropriate effect sizes for various research questions and perform inference on them
2   Convert effect sizes to each other
3   Choose appropriate modeling strategies for various research hypothesis
4   Perform fixed effect meta analysis to obtain a combined effect size
5   Perform random effects meta analysis to obtain a combined effect size
6   Quantify and infer about the degree of heterogeneity present among the effects
7   Perform subgroup analysis on effect sizes
8   Fit a meta-regression model
9   Perform power analysis on the meta analysis model when necessary
10   Check for publication bias
11   Use R to perform meta analysis
