These two groups are two samples representing the population of
workers in the economy. We want to know if the workers who take the
training (treatment sample) have higher earnings than the group
that do not take the training (control sample). If we find that the
trained workers have higher earnings it would indicate that the
training is effective.[1]In terms of statistics, we will do a
hypothesis test on the difference between the mean earnings in the
treatment population and...
