This video introduces the correlation
This video introduces the correlation and regression techniques for analyzing data. This video describes the general concepts to help understand the limitations and applications of correlation and regression.
A companion video describing the calculations is here:

Correlation and regression | Part 2, ...
The correlation method is used to see whether two variables are associated. The regression method is used to identify whether one of the variables causes the other. Both do this by plotting the dependent variable against the independent variable and looking for a non-random linear pattern.
The video also describes how correlation does not imply causation, but also how it can be very useful anyway.
Several real-world examples are discussed to illustrate the major points of this procedure.
It also describes where the terms correlation and regression come from. Finally, it discusses the fallacy of regression.
This is the video that answers the questions: how do correlation and regression work?
