This class studies the use of statistics in solving real problems, from the collection of the data, the evaluation and shaping of data sets, the choice of statistical techniques, and the writing of statistical reports.

We will look at six data sets, spending about two weeks on each one. There will be one lecture session and one lab session each week, following the sequence presentation of the problem and data, preliminary exploration of data, student presentation of preliminary results, further analysis and final report. The class will begin with an introduction to the data manipulation language PERL.
