- At the 10% significance level, are the predictor variables jointly significant?for a two way factor anova comparing the possible interaction between religion and anxiety, what is the alternativeIf the results from a two-factor ANOVA show a significant main effect for both factors, what can you conclude about the interaction between the two factors? a. There must be a significant interaction. b. There probably is a significant interaction. c. The interaction cannot be significant. d. You cannot make any conclusion about the significance of the interaction.
- In ANOVA, what will be the conclusion when the means of the between groups vary from within groups? a.Accept the null hypothesis b.Reject the null hypothesis c.Conduct main effects d.Conduct interaction effectsAt the 5% significance level, are the predictor variables jointly significant? At the 5% significance level, evaluate each of the independent or predictor variables. Think about the five common problems with regression models, what is most likely wrong with this model?Think of a research scenario for which either 1-way or 2-way ANOVA would be needed to analyze the results.
- Explain the difference between the one-way fixed effects model and the one-way random effects model.A recent study randomly selected women from various countries around the world and collected information about diet and health. The women who at a Paleo diet had lower rates of Osteoporosis when compared to the other women in the study. A. Which is the explanatory variable and why. B. Which is the response variable and why. C. Write a conclusion appropriate for this type of study that describes the relationship between the explanatory and response variables.Do less agreeable Facebook users tend to spend more time on Facebook? A study (Ivcevic and Ambady, 2013) aimed to investigate various facets of use of the social networking website Facebook. Previous research suggested that individuals with poorer face-to-face social skills may find internet-based social platforms less daunting, so as part of the study Ivcevic and Ambady investigated whether an individual's volume of Facebook use was associated with levels of "agreeableness". The subjects were 99 university students who all had a Facebook page. The subjects agreed to allowing the content of their Facebook pages to be downloaded on six separate occasions over a three-week period. As part of the data gathered on each subject, each of the 99 were individually rated by a selected friend on an "agreeableness" scale (based on average ratings on a questionnaire where all responses were on a Likert scale), with 1 being "low" and 5 "high". We consider here the relationship between "friend…
