Determine the Effect Size for a Difference in Means: In a study comparing sedation times, Group A has a mean sedation time of 40 minutes (SD = 8, n = 30), while Group B has a mean sedation time of 50 minutes (SD = 8, n = 30). Calculate Cohen’s d as a measure of effect size. Round to two decimal places. Cohen’s d = (Mean₁ − Mean₂) ÷ SD_pooled
