统计学家Jacob Cohen(1988)将效应值(Effect Size,ES)定义为“总体中存在某种现象的程度”;具体到原假设显著性检验(null hypothesis significance testing,NHST)体系中,ES即“原假设H0错误的程度”。 对于临床试验,ICH(International Conference on Harmonization of Technical Requirements for Registration of Pharmaceuticals...
“The primary product of a research inquiry is one or more measures of effect size, not p values.” ~ Jacob Cohen “Statistical significance is the least interesting thing about the results. You should describe the results in terms of measures of magnitude – not just, does a treatment affec...
Book Review: Beyond Significance Testing: Reforming Data Analysis Methods in Behavioral Research There is a rather large literature surrounding the relative merits of null hypothesis significance tests (NHSTs), effect sizes, confidence intervals, and o...

Objective To examine the correlation between publication year and effect size of autism-control group comparisons across several domains of published autism neurocognitive research. Data Sources This meta-analysis investigated 11 meta-analyses obtained through a systematic search of PubMed for meta-analyses...
to make the decision to confirm that an independent variable or treatment did or did not have an important effect, statistics is used. In quantitative research methodology, there are two ways of quantifying this effect: (1) Null Hypothesis Significance Testing and (2) Effect Size (ES), as we...
All biologists should be ultimately interested in biological importance, which may be assessed using the magnitude of an effect, but not its statistical significance. Therefore, we advocate presentation of measures of the magnitude of effects (i.e. effect size statistics) and their confidence ...
The size effect is known to have a major impact on shear strength of conventional reinforced concrete (RC) beams. This has been demonstrated through well documented data from numerous research studies since the 1960s. However, few studies have been conducted to investigate the size effect of RC...
In most cases, effect-size estimates are approximately normally distributed; transformations such as the log of odds ratios are often used to improve the normal approximation (see Statistical Analysis, Special Problems of: Transformations of Data).
