STAT 200 E322 UM The Coefficient of Determination Discussion

I’m trying to study for my Statistics course and I need some help to understand this question. Visit: tylervigen dot com/spurious-correlations (replace ‘dot’ with ‘.’ so the URL works) Look over their graphs and choose one which seems interesting to you. Briefly describe it, and report the calculated correlation, r. If you had to make a theory to explain the connection, what would you say? (remember, none of these items are really connected) In this practical (not mathematical) situation, does the coefficient of determination really = r^2?
