Queens University of Charlotte Research Methods in Communication Q&As
1. What is the difference between descriptive and inferential statistics?
2. What is a null hypothesis? What is an alternative hypothesis? In doing studies, we usually want to reject the null hypothesis, is this correct?
3. What is hypothesis testing? Know the process of conducting a study.
4. What is the confidence level? What is the level of significance (the alpha level)? Know what it means when alpha is set at levels of .05, .01, .001 etc.
5. What is a calculated value? What is a critical value? How do we know that a result is significant (we can reject the null hypothesis)? If I give you a table for critical values, you need to know how to find a certain critical value. (with degree of freedom and level of significance)
6. What is power? How to increase power?
7. What is effect size? How do we know whether an effect size is small, medium or large? (for r, what is the effect size range? for t, what is the effect size range?)
8. Know Type I Error, Type II Error, the confidence interval and power. Know examples for each.
