Find TWO media examples of two types of correlations (explained below). You will have to do some research to find these. Next: (1) Find one media example (don�t make up your own) of a correlation that could be argued to be spurious (third variable). Explain your media example. (2) What is the correlation? That is, what is the predictor variable and what is the outcome variable? Is it a positive or negative correlation? (3) What is YOUR proposed third variable? (4) How does YOUR third variable (spurious variable) SIMULTANEOUSLY explain BOTH your outcome variable and predictor variable? (5) Find another media example that illustrates a correlation that may have an extraneous variable. Explain this example. (6) What is the predictor variable and the outcome variable? Is it a positive or negative correlation? (7) How does YOUR proposed extraneous variable explain your outcome variable and not the predictor variable? This one needs to be an entirely different example from your first example. Be sure to cite your two media sources as well.
