The subject of the book is advanced statistical analyses for
quantitative research synthesis (meta-analysis), and selected
practical issues relating to research synthesis that are not covered
in detail in the many existing introductory books on research
synthesis (or meta-analysis). Complex statistical issues are arising
more frequently as the primary research that is summarized in
quantitative syntheses itself becomes more complex, and as researchers
who are conducting meta-analyses become more ambitious in the
questions they wish to address. Also as researchers have gained more
experience in conducting research syntheses, several key issues have
persisted and now appear fundamental to the enterprise of summarizing
research. Specifically the book describes multivariate analyses for
several indices commonly used in meta-analysis (e.g., correlations,
effect sizes, proportions and/or odds ratios), will outline how to do
power analysis for meta-analysis (again for each of the different
kinds of study outcome indices), and examines issues around research
quality and research design and their roles in synthesis. For each of
the statistical topics we will examine the different possible
statistical models (i.e., fixed, random, and mixed models) that could
be adopted by a researcher. In dealing with the issues of study
quality and research design it covers a number of specific topics
that are of broad concern to research synthesists. In many fields a
current issue is how to make sense of results when studies using
several different designs appear in a research literature (e.g.,
Morris & Deshon, 1997, 2002). In education and other social sciences a
critical aspect of this issue is how one might incorporate qualitative
(e.g., case study) research within a synthesis. In medicine, related
issues concern whether and how to summarize observational studies, and
whether they should be combined with randomized controlled trials (or
even if they should be combined at all). For each topic, included is a
worked example (e.g., for the statistical analyses) and/or a detailed
description of a published research synthesis that deals with the
practical (non-statistical) issues covered.
