Asample 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?

value of d is 0.05

Step-by-step 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

1^3 + 2^3 + 3^3 +4^3 = (1+2+3+4)^2

step-by-step explanation:

i am only able to answer the first part. i am not sure about the second part. sorry
