A sample of n = 25 individuals is selected from a population with µ = 60 and sigma = 10 and a treatment is administered to the sample. after treatment, the sample mean is m = 63. what is the value of cohen's d for this sample?

The information regarding the sampling shows that the value of cohen's d for this sample is 0.3.How to calculate the sample From the information given, the sample of n = 25 individuals is selected from a population with µ = 60 and sigma = 10 and a treatment is administered to the sample. after treatment, and the sample mean is m = 63. Therefore, the value of cohen's d for this sample will be:= (M - µ) / 10= (63 - 60) / 10= 0.3In conclusion, the correct option is 0.3.Learn more about sampling on:
