Practice Exercise 8: Statistical Significance 1. What is meant by the term statistically significant? 2. What is meant by significance level? 3. How would you explain a Type I error? 4. How would you explain a Type II error? 5. What notation would you typically see used in an article to designate the level of statistical significance associated with the results? 6. If your statistical software identified a result that was statistically significant at the .027 level, how would you expect to see this reported in an article? 7. If you conduct a study and identify a statistically significant finding, should you automatically assume that the results are meaningful and important? If no, why? 8. Refer to Figure 9.2. Does this figure correspond to a directional or nondirectional hypothesis? Why? 9. How would the diagram differ for a nondirectional hypothesis?
