JUS 510 Grand Canyon Week 1 Discussion 1

Under what conditions are randomized experimental methods superior to quasiexperimental methods? Explain.

JUS 510 Grand Canyon Week 1 Discussion 2

Is a nonexperiment ever an appropriate choice? Explain.

JUS 510 Grand Canyon Week 2 Discussion 1

Think of examples of measurements of a single variable. Think of one example for which the standard deviation is likely to be much higher for one group and much lower for another group on the same variable. What do your examples illustrate about the nature of standard deviation?

JUS 510 Grand Canyon Week 2 Discussion 2

Discuss the relation between standard scores and the z-scores on which they are based (e.g., IQ scores). How do these scores relate to the normal distribution?

JUS 510 Grand Canyon Week 3 Discussion 1

Think of an example in which you might want to use descriptive statistics and one in which you might want to use inferential statistics. What are the differences between the two types of examples?

JUS 510 Grand Canyon Week 3 Discussion 2

Discuss the differences between a random population sample and a biased population sample. Then discuss the differences between an experimental group and a control group when biased subjects are used. What effect(s) does this have on the results?

JUS 510 Grand Canyon Week 4 Discussion 1

Why is probability sampling so important to research?

JUS 510 Grand Canyon Week 4 Discussion 2

If probability sampling is so important to research, why is it often not used?

JUS 510 Grand Canyon Week 5 Discussion 1

Why are control groups necessary in experimental research?

JUS 510 Grand Canyon Week 5 Discussion 2

Think of a research topic important to you and design an experimental study for it. Why is random assignment important to the study?

JUS 510 Grand Canyon Week 6 Discussion 1

What are the main types of validity, and how are they assessed?

JUS 510 Grand Canyon Week 6 Discussion 2

Why does reliability of measurements matter?

JUS 510 Grand Canyon Week 7 Discussion 1

If you had to choose between using hypothesis testing and confidence intervals, which would you choose? Why?

JUS 510 Grand Canyon Week 7 Discussion 2

Discuss the effects of increasing sample size on confidence intervals and standard errors.

JUS 510 Grand Canyon Week 8 Discussion 1

Consider a research topic of interest. What would the research question be? How could you study it using regression analysis?

JUS 510 Grand Canyon Week 8 Discussion 2

What are some limitations of regression analysis? Explain.
