Statistically Assessing Quality at Wilson Tire
[ send me this paper ]
A 6 page paper finding the design shortcomings of a test of tire longevity and discussing appropriate statistical measures that should be used. Winston Tire Company claims its new tires last for 40,000 miles. This is presented not as a guarantee of minimum mileage purchasers can expect, but rather as an average. An independent agency road-tested 100 tires in an effort to evaluate the company’s claims, creating a sample of n = 100. An independent testing agency has tested Wilson tires and found them lacking, but the truth is that the study is so poorly designed that the agency cannot make any definitive determination about the quality of Wilson tires. The purpose here is to identify appropriate statistical tests of data. Bibliography lists 4 sources.

Statistically Assessing Typing Speeds
[ send me this paper ]
A 6 page paper presenting ANOVA analysis of three sets of data addressing environmental conditions in which data entry personnel work. After testing, the company's owner decides she will forego the music but will bring a coffee service into the office. The pro-music contingent is disappointed, but they agree with the decision based on results. Though there is less variation when typists have rock music in the background, per-minute speed is much greater when individuals are working in silence as they do their work while drinking more easily-obtainable coffee.

Statistics Overview
[ send me this paper ]
A 5 page paper discussing the science of statistics and its use in
today's environment. The study and use of statistics must be done in such a way that an accurate
view results from statistical manipulation. Some statistical errors are benign and result primarily
from ignorance or poor research design. Others, however, are intentionally promoted for the
purpose of "proving" a desired outcome. Bibliography lists 7 sources.
