A research team conducted a study to compare the average test scores of students who were taught using different teaching methods (lectures, group discussions, and hands-on activities). After analyzing the data, the one-way ANOVA test yielded a p-value of 0.062 for the main effect of the teaching method.
Question: What can we conclude from the p-value of 0.062 in the one-way ANOVA test regarding the impact of different teaching methods on students' test scores?
Question : How do we test assumptions to know if they have been met?
Question : How do we determine an interaction?
1. Develop the appropriate research questions and/or hypotheses for main effects and interaction. Regarding Exercise intensity and muscle soreness.
2. Levene’s test for equality of error variances
Is Levene's test of equality of error variances significant & are assumptions met, explain why.
Q: A researcher is interested in determining if stress levels (four categories) and hours slept (four categories have an impact on exam scores after controlling for hours studied.
What is the proper type of analysis that should be conducted?
Q: For the above word problem, what would be a type 1 and type 2 errors associated with the main effects and interactions?
1. Based on the following table, what type of statistical analysis is being performed and what is the significance of the gender factor?
2. Determine whether there is an interaction between degree and job satisfaction.
1.) Determine whether the main effects are significant, if so, please explain why.
2.) What are the assumptions of the ANCOVA and explain why it is important to identify the assumptions in an ANCOVA test.
