A. IMPACT OF MODULE
A sample of 10 students were given a diagnostic test before studying a particular
module and then again after completing the module. We want to find out if, in
general, teaching leads to improvements in students' knowledge/skills. We can
use the results from our sample of students to draw conclusions about the impact
of this module in general. Assume in this example, that the data may not be
normally distributed and that it is necessary to use non-parametric statistics.
