- Do (American) footballs filled with helium go farther? Two
identical footballs, one air-filled and one helium-filled, were used
outdoors on a windless day at The Ohio State University's athletic
complex. The kicker was a novice punter and was not informed which
football contained the helium. Each football was kicked 39 times. The
kicker changed footballs after each kick so that his leg would play no
favorites if he tired or improved with practice. Do an exploratory data
analysis of the helium-filled footballs
dataset.
- Do an exploratory data analysis of the Pima Indians Diabetes dataset. The
primary question of interest is in predicting diabetes from the other
variables. More info is available
in this file. Note that while the info file claims there is no
missing data, in fact, many of the zeroes are indeed missing data (for
example, a zero blood pressure). There are 532 complete cases.
