Meta-analysis is
a quantitative, formal, epidemiological study design used to systematically assess the results of previous research to derive conclusions
about that body of research. Typically, but not necessarily, the study is based on randomized, controlled clinical trials.
What type of quantitative research is meta-analysis?
Meta-analysis is the
quantitative analysis of the results included in an SR
. In practice, this implies the combination of the results of several individual clinical trials using specialized statistical methodology.
What kind of research is meta analysis?
Meta-analysis is
a quantitative, formal, epidemiological study design used to systematically assess the results of previous research to derive conclusions about that body of research
. Typically, but not necessarily, the study is based on randomized, controlled clinical trials.
Are meta-analysis quantitative or qualitative?
Meta-analysis has always been applied to
quantitative research
to aggregate differing results using a standard system e.g. effect size.
Is meta-analysis empirical research?
Look out for types of articles that are
NOT empirical
.
Meta-analyses, literature reviews (with no other study components), editorials/letters, book reviews, case studies, opinions. … In some databases, such as PsycINFO, you can limit to empirical research under Methodology in the “Advanced Search” section.
How many studies do you need for a meta-analysis?
Two studies
is a sufficient number to perform a meta-analysis, provided that those two studies can be meaningfully pooled and provided their results are sufficiently ‘similar’.
How do you do a meta-analysis study?
The steps of meta analysis are similar to that of a systematic review and include
framing of a question
, searching of literature, abstraction of data from individual studies, and framing of summary estimates and examination of publication bias.
Is Phenomenology qualitative or quantitative?
Phenomenology is a type
of qualitative research
in that its focus is in answering the ‘what is it’ question rather than questions of frequency or magnitude such as ‘how much’ and ‘how many.
What level of evidence is a meta-analysis?
| Level of evidence (LOE) Description | Level I Evidence from a systematic review or meta-analysis of all relevant RCTs (randomized controlled trial) or evidence-based clinical practice guidelines based on systematic reviews of RCTs or three or more RCTs of good quality that have similar results. |

What are the types of quantitative research?
There are four main types of Quantitative research:
Descriptive, Correlational, Causal-Comparative/Quasi-Experimental, and Experimental Research
. attempts to establish cause- effect relationships among the variables. These types of design are very similar to true experiments, but with some key differences.
What are the advantages of meta-analysis?
Meta-analysis provides
a more precise estimate of the effect size and increases the generalizability of the results of individual studies
. Therefore, it may enable the resolution of conflicts between studies, and yield conclusive results when individual studies are inconclusive.
What is the difference between content and meta-analysis?
A qualitative meta-analysis can help identify findings across multiple qualitative studies. Content analysis can be similar and is used to find patterns across a corpus. They can both be
inductive or deductive
.
What is the difference between meta-analysis and literature review?
A Literature review is the analysis of all existing literature in a field of study. … Meta Analysis, on the other hand, is
an analysis of similar scientific studies to establish an estimate closest to the common point of truth that exist between them
.
Is a meta-analysis better than a systematic review?
It is a systematic review that uses quantitative methods to synthesize and summarize the results. An advantage of a meta-analysis is the
ability to be completely objective in evaluating research findings
. Not all topics, however, have sufficient research evidence to allow a meta-analysis to be conducted.
Is a meta-analysis a secondary source?
Secondary
Literature/Source
Examples include review articles (e.g., meta-analysis and systematic reviews) and reference works. Professionals within each discipline take the primary literature and synthesize, generalize, and integrate new research.
Are all meta-analysis systematic reviews?
This is called meta-analysis, and it represents a specialized subset of systematic reviews. Not all systematic reviews include meta-analysis, but
all meta-analyses are found in systematic reviews
.
