OPTIONAL FINAL SONG FOR MY STATS MOOC (FREE ONLINE COURSE) (https://www.coursera.org/course/introstats) (harmonica beginning, on E) Numbers, they used to hurt my head A E I did not know centre, shape, or spread F# B It REALly put me on the spot A When someone mentioned a boxplot E But now they don't fill me with dread F# B CHORUS: One, two, alpha beta A I'm making sense of data E It's not a fluke F# B It's 'cause I took a MOOC B E Skeletons drove me 'round the bend But now I call them, "My old friend" If you showed me a vaccine I could not compute the mean Then I found the right class to attend (CHORUS) BRIDGE: I was the worst of every nation G At understanding a relation D Now I've learned that correlation E Does not imply causation A (harmonica -- first on A, then E) I cringed at probability Those coins and dice and "n" and "p" But a hypothesis test Always seems to work the best WHEN you use the distribution "t" (CHORUS) So now I'm feeling really fine I've studied inference on-line I think my favourite lesson Was linear regression Sorting out that slope and sign (CHORUS) I took a MOOC ... it wasn't a fluke ... I must be a kook ... Now make me a Duke ... 'cause I took a MOOC ... MOOC a MOOC a MOOC MOOC ... MOOC a MOOC a MOOC MOOC ... (harmonica on E) -- by Jeffrey Rosenthal (http://probability.ca/jeff/)
