Challenge #30: Alteryx '16 Grand Prix (Race 1, L2)

It seems to me that the answer for the Pearson correlation in the solution is incorrect as it does not eliminate the Null value records (Hitter Rank column) before computing the result. Comments anyone?

Also, I am interested in understanding how the different problems for those Grand Prix Races are picked as someone not familiar with baseball terminology will be clearly at time disadvantage when solving the last question (4). There is a need for clarification in the problem that only hitters can score a home run and only pitchers can have a win. Alternatively, the question should omit conditions such as "for the pitchers" and "for the hitters".

Took around 15 mins to solve this. Still not sure if this was the most efficient way possible.

Looking forward to seeing other solutions for this
