text, the classroom and the world outside' is the sub-heading of Chapter 6 of his book The Social Construction of Meaning: Reading Literature in Urban English Classrooms (Yandell, J. 2013. The Social Construction of Meaning: Reading Literature in Urban English Classrooms. Abingdon: Routledge.)...
When the effect size is measured in standard deviation units as it is for Hedges' g and Cohen's d, it is important to recognize that the variability in the subjects has a large influence on the effect size measure. Therefore, if two experiments both compared the same treatment to a ...
Effect size is a quantitative measure of the magnitude of the experimental effect. The larger the effect size the stronger the relationship between two variables. You can look at the effect size when comparing any two groups to see how substantially different they are. Typically, research studies ...
confidence intervals, and extensive description are needed to convey the most complete meaning of the results” (p. 33). Additionally, it stated that a complete report of all of the hypotheses proven, effect size estimates and their confidence...
Using specific effect size statistics, or even the concept of magnitude of findings as different from statistical significance, is clearly not yet integral to conducting and reporting educational research. This appears to be true even though effect size has been addressed in most statistical methods ...
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...
Detailed information on this trial is provided in the protocol23 (Supplement 1) and a previous article on the main outcomes.24 This prespecified secondary analysis focused on HRQOL, a secondary outcome of the trial. No sample size calculations were undertaken because HRQOL was a secondary outcome,...
In this meta-study, we analyzed 2442 effect sizes from 131 meta-analyses in intelligence research, published from 1984 to 2014, to estimate the average effect size, median power, and evidence for bias. We found that the average effect size in intelligence research was a Pearson’s correlation...
1.3. Inferential Statistics without Effect Size Estimators and Questionable Research Practices Failing to report ES indices, or doing so without discussing them, may be regarded as questionable research practices. Some reasons may include lack of training in statistical procedures, the rush for publishing...
Halo effect, error in reasoning in which an impression formed from a single trait or characteristic is allowed to influence multiple judgments or ratings of unrelated factors. Research on the phenomenon of the halo effect was pioneered by American psycho
