What is cohen?

A standardized effect size called Cohen's d is used to compare the means of two groups. It's frequently applied when contrasting a treatment with a control group. It may be an acceptable effect size to include with the findings of the t-test and the ANOVA. Cohens d is often used in psychology.

Here, we have

Given

Mean = 5

Standard deviation = 100

We have to find the value of d

So, we apply here formula for d

Cohen d = mean / standard deviation      ........................1

Now, we put the value of mean and  standard deviation and we get

Cohen d = 5 / 100

Cohen d = 0.05

Hence, the value of d is 0.05
