Increasing emphasis has been placed on the use of effect size reporting in the analysis of social science data. Nonetheless, the use of effect size reporting remains inconsistent, and interpretation of effect size estimates continues to be confused. Researchers are presented with numerous effect sizes estimate options, not all of which are appropriate for every research question. Clinicians also may have little guidance in the interpretation of effect sizes relevant for clinical practice. The…

Calculating and Reporting Estimates of Effect Size in Counseling Outcome Research

The most common conventions used for estimating and reporting ESs and CIs of ESs are reviewed and it is illustrated how researchers can compute and interpret these measures of practical significance.

The Measurement and Communication of Effect Sizes in Management Research

The measurement and communication of the effect size of an independent variable on a dependent variable is critical to effective statistical analysis in the Social Sciences. We develop ideas about

Improving IS Practical Significance through Effect Size Measures

ABSTRACT Evidence-based practice in management assigns a high value to research results as a guide to practices that have been rigorously shown to be effective. To emphasize the practical relevance

Effect Size Reporting and Interpretation in Social Personality Research

Reporting and interpreting effect sizes has been recommended by all major bodies within the field of Psychology. In this systematic review, we investigated the reporting of ES in six

The importance of reporting the effect size in quantitative studies

1 In 2001, the American Psychology Association advised researchers to provide readers with information about statistical significance and, even more importantly, to provide information about the

An Assessment of the Magnitude of Effect Sizes

This study compiles information from more than 250 meta-analyses conducted over the past 30 years to assess the magnitude of reported effect sizes in the organizational behavior (OB)/human resources

Correlational effect size benchmarks.

This study extracted 147,328 correlations and developed a hierarchical taxonomy of variables reported in Journal of Applied Psychology and Personnel Psychology from 1980 to 2010 to produce empirical effect size benchmarks at the omnibus level, for 20 common research domains, and for an even finer grained level of generality.

Using Anchor-Based Methods to Determine the Smallest Effect Size of Interest

Effect sizes are an important outcome of quantitative research, but few guidelines exist that explain how researchers can determine which effect sizes are meaningful. Psychologists often want to

Guide for calculating and interpreting effect sizes and confidence intervals in intellectual and developmental disability research studies

A nontechnical description of methods for calculating effect sizes in intellectual and developmental disability studies and sources of information on effect size calculators are included to provide researchers ready-available data analysis procedures for computing effect sizes and confidence intervals for different types of research designs and studies.



How to Estimate and Interpret Various Effect Sizes

The present article presents a tutorial on how to estimate and interpret various effect sizes. The 5th edition of the Publication Manual of the American Psychological Association (2001) described the

Practical Significance:The Use of Effect Sizes in School Counseling Research

In response to the increasing call by professional organizations, journal editors, and statisticians to include not only derived significance levels from quantitative statistical procedures but also

Using odds ratios as effect sizes for meta-analysis of dichotomous data: A primer on methods and issues.

Many meta-analysts incorrectly use correlations or standardized mean difference statistics to compute effect sizes on dichotomous data. Odds ratios and their logarithms should almost always be

A simple effect size indicator for two-group comparisons? A comment on r equivalent.

The limitations of their proposal, however, are many, and much more serious than the authors suggested, and should be carefully considered before this effect size is applied, as well as in developing other effect sizes using similar methods.

Evaluating Results Using Corrected and Uncorrected Effect Size Estimates

AbstractMagnitude-of-effect (ME) statistics, when adequately understood and correctly used, are important aids for researchers who do not want to place a sole reliance on tests of statistical

Toward improved statistical reporting in the journal of consulting and clinical psychology.

Substantially improving statistical practices may require stricter editorial policies and further guidance for authors on reporting and interpreting measures, according to the present authors, who examined 239 JCCP articles published from 1993 to 2001.

Is Psychological Research Really as Good as Medical Research? Effect Size Comparisons between Psychology and Medicine

The author suggests that many of the calculated effect sizes from medical epidemiological research on which this conclusion that relatively small effects seen in psychology research are as strong as those found in important epidemiological medical research are flawed.
