Visual Representations of Multiple Correlation
If you have only two independent variables, then the general concept of multiple correlation can sometimes be visualized using 3-D graphs. Some examples are given below. you will be looking for the plane (surface) of best fit instead of the line of best fit.
- Exact Positive Linear Multiple Correlation
- Strong Positive Linear Multiple Correlation
- Weak Positive Linear Multiple Correlation
- No Linear Multiple Correlation
Those items should each be a link to a page with a graph on it. I'm not exactly sure where this will go or how it these examples will look it is not easy to just make them up or to visualize -- let's work on this.
