Question

A sample of difference scores has a mean of MD = 5 with a variance of s2 = 100. If effect size is measured using Cohen’s d, what is the value of d?​

Answer 1

value of d is 0.05

Explanation:

given data

mean = 5

standard deviation = 100

to find out

the value of d

solution

we will apply here formula for d

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

put here value of mean and standard deviation

Cohen d = mean / standard deviation

Cohen d = 5 / 100

Cohen d = 0.05

so value of d is 0.05
