Three of the Most Embarassing Outcomes for a Statistician and Their Workarounds:
(1) Result: The intercorrelations between a fairly large set of variables has exactly 5% of the coefficients that are significant at the .05 level. Solution: Try to remain upbeat. Lighten up and use the .10 level of significance and stress to the readers that these results represent an early exploratory study!

(2) Result: In a 3x3x4x4x5 Factorial ANOVA the Five-Way Interaction turns up significant at the .01 level. Solution: Curse under your breath that you used a five-factor design. Then instruct your graduate assistant to conduct FIVE Four-Way ANOVAs, one for each of the five levels of the 5th independent variable, to take two aspirin, and call back in the morning!

(3) Result: The F-test for a One-Way ANOVA with five treatment groups is significant at the .05 level but NONE of the pairwise comparisons between the five means is significant. Solution: Cry hard and then work your tail off to find some obscure, meaningless complex comparison that is significant such as the average of the first three treatment means is significantly different from the average of the last two treatment means!

*The above are my own dreaded results. I am sure the readers have their own convoluted and shocking statistical anomalies. Please email me your most feared and or realized statistical outcome and I will put it in the Gallery.
