Two data samples are independent if they come from unrelated populations and the samples do not affect each other. Here, we assume that the data populations follow the normal distribution. Using the unpaired t-test, we can obtain an interval estimate of the difference between two population means. You will be looking at populations to make assumptions.

Module Outcomes:

- The means of two independent populations.
- The means of two related populations.
- The proportions of two independent populations.
- The variances of two independent populations.
