I am extremely unfamiliar with the program JMP. Could anyone show me how to find the answers to problems like these using the program?
1. What is the mean of the difference scores obtained in the sample?
2. What is the obtained value of t?
3. What is the obtained p value for t?
4. What are the correct degrees of freedom for the t-statistic?
5. What is the correct statistical decision?
6. What is the probability of your having made a TYPE I Error?
7. What is the probability your having made a TYPE II Error?
8. What is value of the Wilcoxon for this set of data?
9. What is the associated p-value of the Wilcoxon?
10. Based on the Wilcoxon, should you reject the null hypothesis:
11. What is the primary threat to the internal validity of this study?
12. What could be done to improve this study (e.g. what changes in methodology)?
13. Is the assumption of normality reasonable?
