As a researcher, you can choose to do a meta-analysis on any topic you're interested in. The first step is to form a clear hypothesis and concise description of the problem that includes the specific population that the study focuses on, the problem it addresses, the intervention and expected outcome. Choose a hypothesis for the meta-analysis The process for conducting a meta-analysis usually involves five steps: 1. Meta-analysis can uncover new patterns, trends and associations.

It shows you how to refine your research questions or what influences the results that you obtained. Meta-analysis can help you find significant patterns and trends in your data by exploring individual pieces of information. Often, the relationships among variables are not obvious from an examination of the individual data sets. You can use meta-analysis to provide an explanation that might go with your hypothesis concerning the data collected. It also provides additional insight into the topic with its ability to compare results across different studies. Meta-analysis also allows for more general conclusions to be drawn from bodies of work about a specific topic.Ī meta-analysis can save time and the use of personnel by combining quantitative research studies to find patterns in the data.Ĭonducting meta-analysis is beneficial because it can act as a more objective source of information. Meta-analyses can identify potential biases in a field of research by emphasising certain features or designs in each study. It can show relationships between variables that might not easily show within a single study. Meta-analysis can sometimes include quantitative and qualitative analysis. It shows strengths and weaknesses of different studies on similar topics. Here are the attributes of meta-analysis: When you conduct a meta-analysis study, you can better see how effective or ineffective an intervention was, whether there were any hidden effects and how related concepts work together. Recalling that companies and institutions are the sponsors of studies in the same industry, meta-analysis can improve our knowledge about potential biases in individual studies and how they might affect the study's conclusion. The purpose of doing a meta-study is to reduce bias in research and create more reliable conclusions.

For instance, in medicine, meta-analyses are frequently used to determine which treatments are best for treating a condition or how well treatments work. In both cases, meta-analysis provides better estimates for population parameters than any individual study can achieve alone. One averages the findings from multiple studies and the other explores relationships among variables in different studies.

It's a statistical technique that seeks to answer a new question posed by the researcher. To answer the question 'What is meta-analysis?', it's the process of identifying, selecting and combining results from primary studies to verify a new hypothesis. In this article, we answer ‘What is meta-analysis?', define the term, look at its benefits, discuss why and how to use it, show how it benefits medical research and present its limitations. Although it allows for high levels of scientific inference and it only requires one researcher to take on the task. It's powerful because it combines results from many different experiments that are similar in nature. Meta-analysis is a statistical analysis that combines the results of several studies.
