20. Case Studies The case studies give examples of practical applications of statistical analyses. Many of the case studies contain the actual raw data. Some contain discussions of how the the data were analyzed. All links below are external links. 1. Angry Moods 2. Flatulence 3. Physicians Reactions to Patient Size 4. Teacher Ratings 5.

21. Glossary a priori Comparison A comparison that is planned before (a priori) conducting the experiment or at least before the data are examined. Absolute Deviation The absolute value of the difference between two numbers. The absolute deviation between 5 and 3 is 2; between 3 and 5 is 2; and between -4 and 2 it is 6. Alternative Hypothesis In hypothesis testing, the null hypothesis and an alternative hypothesis are put forward. If the data are sufficiently strong to reject the null hypothesis, then the null hypothesis is rejected in favor of an alternative hypothesis. For instance, if the null hypothesis were that μ 1 = μ 2 then the alternative hypothesis (for a two-tailed test) would be μ 1 μ 2 . Analysis of Variance Analysis of variance is a method for testing hypotheses about means. It is the most widely- used method of statistical inference for the analysis of experimental data. Antilog Taking the anti-log of a number undoes the operation of taking the log. Therefore, since Log 10 (1000)= 3, the antilog 10 of 3 is 1,000. Taking the antilog of X raises the base of the logarithm in question to X. Average (i) The (arithmetic) mean (ii) Any measure of central tendency Bar Chart A graphical method of presenting data. A bar is drawn for each level of a variable. The height of each bar contains the value of the variable. Bar charts are useful for displaying things such as frequency counts and percent increases. They are not recommended for displaying means (despite the widespread practice) since box plots present more information in the same amount of space.
