- 6. Which method did Kantano et al. use in the post-hoc comparison to adjust for type I error inflation?
- 10. Gayet-Ageron et al. – Challenge: The researchers presented information with the region of affiliation and the gender of the first author (see Table D in supplementary materials). What is the expected value for first author with missing gender in Latin America if there is no association between region and gender? (Whole number only)
- 11. Gayet-Ageron et al. - In looking at the association between time and type of journal (generalist vs. specialist) submissions, the authors were able to use chi-sq test because the transformed time into multiple _____.
- 12. Gayet-Ageron et al. – The researchers reported how the odds of the first author being a woman in Covid-19 manuscripts is lower than that in pre-pandemic manuscripts. They must have run a form of ___ regression to arrive at that conclusion.
- 13. Just like in t-test, if the homogeneity of variance is violated in a one-way ANOVA, this corrects for it. (Except in t-test, it is ___’s t, and in ANOVA, it is ____’s F)
- 15. Elbin et al. Near-point convergence (NPC) distance is used as a measure of symptoms after a concussion. The researchers looked at NPC distance at before injury (they had baseline data), 1 to 7 days after injury, and 8 to 14 days after injury. To see if there are any differences in NPC distance, they would have to run a ____ ANOVA.
- 17. Gayet-Ageron et al. - In looking at the proportion of manuscripts submitted to journals pre-pandemic and during the pandemic (separated into non-Covid-19 related manuscripts and Covid-19 related ones) by the authors’ geographical origin (See Table C in supplementary materials), the researchers used the one-way ANOVA test. Truee/False
- 18. Festinger & Carlsmith – The study protocol includes the experimenter lighting up a cigarette. Truee/False
- 19. A method to correct for familywise error. Considered to be conservative and the simplest one, it is widely used.
Down
- 1. Kantono et al. specified that they would use the Greenhouse-Geisser correction if their ANOVAs were found to violate the _________ assumption.
- 2. Festinger & Carlsmith – The difference in enjoyability ratings by participants in the $1 and $20 conditions was significant at the ___ level.
- 3. Yang et al. – There is a significant difference in the proportion of thermal taster between Asian and Caucasian in the study. Truee/False
- 4. If you see a significant F-test, you should run this to see which group(s) is different from which other group.
- 5. Festinger & Carlsmith – Ideally, they should’ve run the ____ F-test to see the overall effect before using the t-test to see differences between pairs of groups.
- 7. Gayet-Ageron et al. – The researchers used a Kruskal-Wallis non-parametric test for comparison of total number of co-authors among time groups. This probably means that the data failed the ____ assumption.
- 8. Festinger & Carlsmith - In the classic study of cognitive ______, there were three conditions: control, one dollar, and twenty dollars. (amount paid after a boring task)
- 9. It appears that in recent publications, one-way ANOVA (and to some extent, chi-sq tests) is used more often as a ______ to make sure the baseline levels or demographic characteristics (e.g., age) are not different among different experimental groups.
- 14. A technique to correct for familywise error. R’s default.
- 16. Yang et al. – In the study, the researchers classified the participants into different sweet likers status. If they investigated how the sweet likers status is associated with PROP intensity rating (see Figure 1 left y-axis for the scale), which test would they likely run? (ChiSq or ANOVA)
- 17. Yang et al. – There are three different phenotypes of taster (pST = supertasters, pMT = moderate tasters, and pNT = non-tasters) and three types of genotypes of gustin (A:A, A:G, and G:G). The degrees of freedom is 4, and there is a significant difference between the taster phenotype and the gustin genotype. Truee/False
