In a systematic review with a meta-analysis, researchers combine the results of each of the individual studies to create a larger sample size (and therefore greater power), then re-run the statistics to capture the true magnitude of the effect. The single-effect measure calculated and reported when the results from all the studies are combined is called what? A. Summary statistic B. Power analysisC. Confidence Interval D. Chi square E. Pearson's co-efficient

A meta-analysis is an overall summary of the statists that represent the invention across multiple studies.

The single-effect measure calculated and reported when the results from all the studies are combined is called Power analysis.

Option: B

Explanation:

Evaluation of power is an essential part of experimental setup. This helps us to assess with a certain level of confidence the sample group needed to identify an impact of a particular size. Alternatively, it helps one to assess the possibility of finding an influence of a given size with a certain confidence level, within sample size restrictions.When the likelihood is unacceptably small, it will be wise to alter the experiment or leave it.

The given four quantities are sharing a close connection in such analysis, out of which if three quantities are determined then 4th can be calculated easily:
