Answer 1

In Workforce development field , we might want to knoe the mean difference between between two or more groups if we are inetersted in comapring the two different techniques for improving the work skills.

fiest we will divide the sample into two groups and then both the groups will recieve the techniques independently and in the end both the groups are given the same exam and then their scores are recoreded. So the difference in the mean score is used to compare the two techniques.
