of real data. In presenting the tables to you, I have not lied about my weight, nor
have you used any bad math to falsify the predictions. The word we’re looking for
here is ‘disingenuous’. Look it up and then discuss the implications this type of data
manipulation could have in a larger, more complex, politically motivated setting. (Even
Obi-Wan presented the truth to Luke only “from a certain point of view.”)
4. (Data that is neither linear nor quadratic.) We’ll close this exercise set with two data sets that,
for reasons presented later in the book, cannot be modeled correctly by lines or parabolas. It
is a good exercise, though, to see what happens when you attempt to use a linear or quadratic

(a) This ﬁrst data set came from a Summer 2003 publica...
