Provide an example of a three-factor ANOVA. Identify the grouping and test variables. Why does it make sense that an F statistic of 1 implies there is no effect of your independent variable? A multiple regression analysis of 57 cases was performed with four explanatory ...
The composition of each sex was tested using Pearson's correlation coefficient, and with the null hypothesis that the composition did not depend on sex, an F test was performed using a two-factor ANOVA of age and sex. R (version 4.3.2, R Foundation for Statistical Computing, Vienna, ...
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 ...
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...
What would be the null hypothesis for testing a linear regression model with profit as the dependent variable and sales as the independent variable? Given the following, complete the ANOVA table and make the correct inference. Using F-value to make a decision. a) What...
2A (black bars with white cross-hatching). To assess the effect of the delay period on the separate parameters of the mixture model, we ran three separate, one-way ANOVAs comparing mean color bias (μ), Pm, and s.d. across conditions. Mixture model fits for the parameter μ revealed ...

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...
Describe a fictional study in which you name the variables to be studied in the context of a possible research question and to state what type of ANOVA is most appropriate to answer the research question. Why are physical anthropologists interested in studying primatology? Ex...
