I am conducting a research study. I have two
populations. Sample population 1 is a control group. Sample
population 2 has received the intervention.
The question is, how do I determine if there is a relationship
between the two populations using the data sets below:
Sample from Population 1: 33, 29, 35, 39, 39, 41, 25, 33,

Sample from Population 2: 46, 43, 42, 46, 44, 47, 50, 43,
