External validity deals with how much can be inferred
from your results.
Okay, we're rapidly approaching the end of this course, and we'll wrap

statistics were examined in Lesson 33 where we spoke of measures of central
tendency; such as mean and median, as well as measures of dispersion, such

Our main concern, when working with

In Lesson 34, we discussed statistical methods which allow you to
describe the relationship between variables as scores and statistical

data you have. Okay, we're getting ready to ask the final question in this
lesson (and this course). In fact, this will be question number '430.' Are
Here we go.
