I define research consolidation as comparing and combining (amalgamating or, at least, juxtaposing) results or other output from multiple previously conducted research activities, relevant to a goal or topic of interest. The concept, not limited to empirical research or any specific method, is...

Meta-analysis is a research method to synthesise previously obtained research results. It is best seen as a statistical approach towards reviewing and summarising the literature. This paper aims to introduce and critically review the research method of meta-analysis and to illustrate its...

Survey data are often used for comparison purposes, such as comparisons across nations or comparisons over time. To be effective, this would require equivalent questions and equivalent responses options to the questions. Yet there is a lot of variation in the response scales used, which, for...

This paper presents methods for second order meta-analysis along with several illustrative applications. A second order meta-analysis is a meta-analysis of a number of statistically independent and methodologically comparable first order meta-analyses examining ostensibly the same relationship...

Social scientists are producing an ever growing stream of research findings, which is ever more difficult to oversee. As a result, capitalization on earlier investment declines and accumulation of knowledge stagnates. This situation calls for more research synthesis and interest in synthetic...

Literature on the combination of qualitative and quantitative research components at the primary empirical study level has recently accumulated exponentially. However, this combination is only rarely discussed and applied at the research synthesis level. The purpose of this paper is to explore...
