A researcher examines the influence of marital counseling on individuals' romantic relationship satisfaction. One group of 20 married individuals participates in marriage counseling, while a second group of 20 married individuals receives no counseling. After 2 months, each participant reports on their relationship satisfaction. For the participants receiving counseling, their mean satisfaction was 4.5. The mean satisfaction for participants who received no counseling was 6.8. The pooled variance was 28.
What is the Cohen's d for this example?
Be sure to round to two decimal places for each calculation step.

-0.43

Explanation:

Given M1= 4.5

M2= 6.8

pooled = 28

The formula for d = M1 – M2 / s (pooled)

M1 = mean of group 1. M2 = mean of group 2. s (pooled) = pooled standard deviations for the two groups.

d = 4.5 - 6.8 / sqrt (28)

d = -0.43
