- "A meta-analysis is a statistical analysis that combines the results of multiple scientific studies." - "The aim then is to use approaches from statistics to derive a pooled estimate closest to the unknown common truth based on how this error is perceived."
This topic includes specialized research methods like meta-analysis, factor analysis, and item response theory.
Research Design: The methodology and process of planning and designing a research study, including selecting participants, research methods, data collection, and data analysis.
Sampling Techniques: Methods for selecting and recruiting participants for a research study, including random sampling, convenience sampling, stratified sampling, and quota sampling.
Data Collection Methods: Techniques for collecting data, such as observation, surveys, interviews, questionnaires, and experiments.
Quantitative Research Methods: A systematic approach to research through the use of numerical data analysis, including statistical analysis, hypothesis testing, and survey research.
Qualitative Research Methods: A systematic approach to research that involves the collection and analysis of non-numerical data, such as interviews, focus groups, and case studies.
Data Analysis Techniques: Methods for analyzing and interpreting data collected in a research study, including descriptive statistics, inferential statistics, and qualitative analyses.
Ethical Considerations in Research: Guidelines and principles regarding ethical conduct in research, including informed consent, confidentiality, debriefing, and data manipulation.
Research Replication and Seminal Studies: Replication of prior research findings and seminal works in psychology research.
Research Tools: The vast tools and software that are used in research such as Statistical Package for the Social Sciences (SPSS), Qualitative Data Analysis Software (QDAS) and Lit Review Software.
Methodological innovation and alternative methods: Developing new methodologies to investigate new research areas and to improve existing methods. These include approaches like Digital ethnography, online surveys, deep interview analysis and mixed method research.
Case studies: In-depth analyses of one particular individual or a small group of people, on the premise that they can reveal unique insights into human behavior.
Correlational studies: Observing the relationship between two or more variables and analyzing the extent to which they are related.
Surveys: Questionnaires used to gather data from a large sample of individuals on a particular topic.
Experimental studies: Activities designed to create and manipulate a particular situation to test the effect on behavior or cognitive processes.
Observational studies: Systematic observations of behavior in real-life or laboratory settings.
Longitudinal studies: Research on the same group of people over an extended period, allowing for an investigation of changes in behavior over time.
Cross-sectional studies: Research comparing groups of people at one point in time to identify differences or similarities.
Quasi-experimental studies: Studies that use existing groups or conditions, rather than randomized conditions or groups, for practical or ethical reasons.
Meta-analyses: Combining the results of multiple studies to identify trends, patterns, and generalizations.
Content analysis: A method of analyzing textual or visual information in which coders analyze information to identify patterns and themes.
Cross-cultural studies: Studies comparing different cultures' behaviors and attitudes to determine universal or culture-specific phenomena.
Action research: Research conducted within a group or organization to identify areas for improvement and implement effective interventions.
- "Meta-analytic results are considered the most trustworthy source of evidence by the evidence-based medicine literature."
- "It also has the capacity to contrast results from different studies and identify patterns among study results, sources of disagreement among those results, or other interesting relationships that may come to light with multiple studies."
- "If individual studies are systematically biased due to questionable research practices or the publication bias at the journal level, the meta-analytic estimate of the overall treatment effect may not reflect the actual efficacy of a treatment." - "Meta-analysis has also been criticized for averaging differences among heterogeneous studies because these differences could potentially inform clinical decisions."
- "This makes meta-analysis malleable in the sense that these methodological choices made in completing a meta-analysis are not determined but may affect the results."
- "Deciding how to search for studies, selecting studies based on a set of objective criteria, dealing with incomplete data, analyzing the data, and accounting for or choosing not to account for publication bias."
- "Meta-analyses are often, but not always, important components of a systematic review procedure."
- "For instance, a meta-analysis may be conducted on several clinical trials of a medical treatment, in an effort to obtain a better understanding of how well the treatment works."
- "Here it is convenient to follow the terminology used by the Cochrane Collaboration, and use 'meta-analysis' to refer to statistical methods of combining evidence, leaving other aspects of 'research synthesis' or 'evidence synthesis', such as combining information from qualitative studies, for the more general context of systematic reviews."
- "Meta-analysis may also be applied to a single study in cases where there are many cohorts which have not gone through identical selection criteria or to which the same investigational methodologies have not been applied to all in the same manner or under the same exacting conditions."
