HLT 362 ALL WEEK 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.
Week 4 DQS
1 – If the result of an ANOVA experiment was “not significant”, was the experiment a failure? Provide reasoning and examples (real or hypothetical) to support your argument.
2 – What is an interaction? Describe an example; what are the variables within your population (work, social, academic, etc.) for which you might expect interactions?
Week 5 DQS
1 – Now that you are familiar with the basic concepts of statistics, what are some examples of when you have seen or heard statistics used inappropriately?
2 – What is an example in the world around you for which you would use a Chi-square analysis?
