Topic 1 DQ1
How can graphics and/or statistics be used to misrepresent
data? Where have you seen this done?
Topic 1 DQ2
What are the characteristics of a population for which it
would be appropriate to use mean/median/mode? When would the characteristics of
a population make them inappropriate to use?

Topic 2 DQ1
Explain the importance of random sampling. What
problems/limitations could prevent a truly random sampling and how can they be
prevented?
Topic 2 DQ2
Explain each sampling technique discussed in the

when each technique would be appropriate.

Explain when a z-test would be appropriate over a t-test.
Topic 3 DQ2
Researchers routinely choose an alpha level of 0.05 for testing
their hypotheses. What are some experiments for which you might want a lower
alpha level (e.g., 0.01)? What are some situations in which you might accept a
higher level (e.g., 0.1)?

Topic 4 DQ1
How would you explain the analysis of variance, assuming
that your audience has not had a statistics class before?
Topic 4 DQ2
What is an interaction? Describe an example and identify the
variables within your population (work, social, academic, etc.) for which you
might expect interactions?

Topic 5 DQ1
Describe the error in the conclusion. Given: There is a
linear correlation between the number of cigarettes smoked and the pulse rate.
As the number of cigarettes increases the pulse rate increases. Conclusion:
Cigarettes cause the pulse rate to increase.
