Today we investigated the association between the number of spaces from GO a property is in the game Monopoly and the cost of rent + hotel for said property. The following work was put on page 51 of the ISN.
As a review, students described the association between the two variables and then classified and analyzed the outlier. We then constructed a residual plot using the calculator and found that the data WAS NOT LINEAR! Uh oh!
We then took some notes and looked at another example (Arizona State Tuition from 2000-2010), and discussed at a pretty bare bones level how to deal with transformed data. Remember, we will not be transforming bivariate data in this class, but we do need to know how to do all of the same analysis that we've done previously, but with a transformed model. Here is a photo (probably fuzzy - I'm working on it), of the notes on page 52 of the ISN today.
There's no official homework tonight, but you should be reviewing LT #18-22 in preparation for Monday's MEGA QUIZ!
