Examples of Cohen's d in the following topics:
-
- Cohen's $d$ is a method of estimating effect size in a $t$-test based on means or distances between/among means.
- Cohen's $d$ is a method of estimating effect size in a $t$-test based on means or distances between/among means .
- Cohen's $d$ is an example of a standardized measure of effect.
- Cohen's $d$ is frequently used in estimating sample sizes.
- Justify Cohen's $d$ as a method for estimating effect size in a $t$-test
-
- Two commonly used measures are Hedges' g and Cohen's d.
- They differ only in that Hedges' g uses the version of the standard deviation formula in which you divide by N-1, whereas Cohen's d uses the version in which you divide by N.
- Standardized measures such as Cohen's d and Hedges' g have the advantage that they are scale free.
- For example, Lenth (2001) argued that other important factors are ignored if Cohen's definition of effect size is used to choose a sample size to achieve a given level of power.
- 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.
-
- Cohen's $D$ (effect size), which is the expected difference between the means of the target values between the experimental group and the control group divided by the expected standard deviation.

- In 1978, Anthropologist Ronald Cohen claimed that the identification of "ethnic groups" in the usage of social scientists often reflected inaccurate labels more than indigenous realities:
- Cohen also suggested that claims concerning "ethnic" identity (like earlier claims concerning "tribal" identity) are often colonialist practices and effects of the relations between colonized peoples and nation-states.
- Criticize the concept of ethnicity from the perspective of Max Weber's and Ronald Cohen's theories of social constructionism, referencing the approaches of primordialism, perennialism, and constructivism
-
- Jacob Cohen, an American statistician and psychologist, suggested effect sizes for various indexes, including $f$ (where $0.1$ is a small effect, $0.25$ is a medium effect and $0.4$ is a large effect).
- Compound comparisons typically compare two sets of groups means where one set has two or more groups (e.g., compare average group means of groups $A$, $B$, and $C$ with that of group $D$).

- The term was coined by Stanley Cohen in 1972 to describe media coverage of Mods and Rockers in the United Kingdom in the 1960s.
