week 1

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

Is a nonexperiment ever an appropriate choice? Explain.

week 2

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?

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?

week 3'

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?

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?

week 4

Why is probability sampling so important to research?

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

week 5

Why are control groups necessary in experimental research?

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

week 6

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

Why does reliability of measurements matter?

week 7

week 7

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

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

week 8

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

What are some limitations of regression analysis? Explain.
