week13: “ANALYSIS, PRESENTATION, AND INTERPRETATION OF DATA”

we discussed the analysis, presentation, and interpretation of data. We began by discussing the presentation of results in tabular form. We discussed one, two and three variable tabular presentations, and also discussed strategies for collapsing the categories of a table. We next turned to a discussion of statistical hypothesis testing. We discussed tests of significance, defined a null hypothesis, and discussed Type I and Type II error. The χ² test of significance and Fisher’s Exact Test were also presented.
