SI 544 project

You will be working in groups, and will share the same grade with your group members. This project will account for 20 points of your final grade.

The idea is to collect some data and analyze it. You can collect new data (e.g. conduct a survey or an experiment) or get a hold of a previously collected data set (e.g. web server logs, data from a previous study). The hypothesis you test should not have been examined before with regard to that particular data set.

Past projects have included showing that basketball players with a history of arrests for violent offences score more often per minuteof play, correlating temperatures and beer consumption in Ann Arbor, etc. This year, Hung Truong, Sameer Halai, and James Laing created a FaceBook app and survey to see whether people's impression of sociability of instruments corresponds to sociability on FaceBook.
