The goal of statistics is to make judgements based on data. A perfect example is the ability of network news to predict the outcome of elections before the polls close. The statistician uses many techniques in the analysis of information. Chi Square is one such method. The basic idea behind Chi Square is to find out if a set of numbers just happened to occur the way they did by chance or if there was some other factor which may have influenced them. This tutorial provides step by step instruction in the use of the Chi Square method of analysis. Once you have completed the tutorial, you can exercise your new-found knowledge by putting together additional sets of test data to analyze.
