Chi-Square Statistics, Tests of Hypothesis and Technology.
Rochowicz, John A.
The use of technology such as computers and programmable calculators enables students to find p-values and conduct tests of hypotheses in many different ways. Comprehension and interpretation of a research problem become the focus for statistical analysis. This paper describes how to calculate chisquare statistics and p-values for statistical tests of hypothesis with spreadsheets, especially LOTUS 1-2-3 for Windows. The chi-square probability distribution is approximated by techniques including series expansions and Simpson's Rule. The construction of spreadsheet macros to perform these calculations is demonstrated. Meanings and applications of the chi-square probability distribution to a number of examples are illustrated for students with various mathematical backgrounds. A description of the use of a computer algebra system, DERIVE, for computing p-values is also provided in the appendix. The use of technology as a tool for learning and doing statistics is emphasized. An appendix discusses other ways to find p-values. (Contains 10 tables and 9 references.) (Author/SLD)
