HLT 362 WEEK 1 TO 5 ALL DISCUSSION QUESTIONS
Week 1 Dqs
1 – How could graphics and/or statistics be used to misrepresent data? Where have you seen this done?
2 – What are the characteristics of a population for which a mean/median/mode would be appropriate? Inappropriate?
Week 2 DQS
1 – Explain the importance of random sampling. What problems/limitations could prevent a truly random sampling and how can they be prevented?
2 – How large would your population have to be for a sample to be appropriate (i.e., rather than measuring the whole population)?
Week 3 DQS
1 – Suppose you hear an “old-timer” say, “Why, in my day, kids were much more respectful and didn’t cause as much trouble as they do nowadays!” Formulate a hypothesis related to this statement that you could test. How would you test it?
2 – Researchers routinely choose an α-level of 0.05 for testing their hypotheses. What are some experiments for which you might want a lower α -level (e.g. 0.01)? What are some situations in which you might accept a higher level (e.g. 0.1)?
3 – Explain when a z-test would be appropriate over a t-test.
