The Pairwise Multiple Comparison of Mean Ranks Package (PMCMR) The Kruskal and Wallis one-way analysis of variance by ranks can be employed, if the data do not meet the assumptions for one-way ANOVA. Provided that significant differences were detected by the Kruskal-Wallis-Test, one may be...
2022). Since multiple fork length data were determined from single vertebrae, there was an issue of autocorrelation and violating the data independence assumption. In fact, in the paired analysis of variance (ANOVA) (first to fourth increments), the individual effect was significant (F = ...
Explain the major differences between analyzing a one-way ANOVA versus a two-factor ANOVA, and explain why factorial designs with two or more independent variables (or factors) can become very difficult to interpret Explain the term transactional analyses in the parent-c...
Given the following, complete the ANOVA table and make the correct inference. Using F-value to make a decision. a) What is the hypothesis being tested in this problem? True or False: If a regression gave us the following 95% confidence interval for the estimated coefficient: 0.292 to 0...
The models were generated using the lme4 R package (v 1.1-31) as lmer (gut environmental factor ~ factor(day) + (1 | Participant ID)); moreover, ranova function from the lmerTest package (v 3.1-3) was used to perform the random effects-likelihood ratio tests to infer whether ...
A lower BP level was noted for higher exercise tolerance - NYHA I, 140,92±20,66 mmHg, p=0.04), NYHA II (141,25±17,24 mmHg, p=0.06), both compared with lower exercise tolerance - NYHA III-IV (162.33±29,45 mmHg, p=0.04); differences were significant (ANOVA test (F (3)=4.53...

A Mixed 2 × 2 ANOVA attested a significant Time X Group interaction, indicating a significant reduction of the cognitive distortions from pre-test to post-test only in the Training group. The follow-up attested to the stability of the training effects and the reduction of gambling frequency ...
Explain what the key ratio, the F ratio, in a one-way ANOVA table is all about and why it is the basis for a test of equal means. Explain the ordinal variables with examples. What does 'bias' mean in data collection? How can I test to see if a fabric is water resistant? How do...
(c) How do you identify the variable that is the dependent variable? Give an example of a business situation in which you would use a one-way ANOVA. What is the independent variable? What are the levels of that variable? What is the dependent variable? What makes ...
