Null Hypothesis, Significance Level, ANOVA vs. t-Tests

So give this a shot: design an imaginary study or discuss a published study you’ve read that has an experimental or quasi-experimental design that used or would use t-tests or ANOVAs in the data analysis. Briefly tell us the nuts and bolts of the study and then get to the discussion of:

What the null hypothesis is in your experiment.

What the level of significance you chose in your experiment (go ahead, it’s not being graded…)

Describe the statistical method you used in the analysis of the data, either t-tests or ANOVAs. What determined your choice?

Now for correlations. The concept behind the word correlations is good to know well because it is the foundation of most studies: we see correlations between things and we wonder how these correlations work a lot as professionals.  What are the different types of correlation? Now for the technical area: How is the strength of a correlation determined?

The subject of this question is measures of central tendency. (Let’s not bother with mode because it will rarely come up in real life.) This is THE basic part of any quantitative study’s data analysis. Let’s make sure we’re clear about what the mean and what the median are. Does all data have a mean and a median? Why or why not? When is the mean the best measure of central tendency? When is the median the best measure of central tendency? Now for an important part of many studies: what is the standard deviation? (Don’t be shy about giving this a try; we’ll help with explanations.) Why is sd (standard deviation) such an important term?

I hope you will think this discussion starter to be fun. It’s a good way to integrate into your understanding the reading in Chapter 11 on quasi-experimental studies. After all, these types of studies are among the most common in psychological research. You’ll be reading lots of these types of studies as a professional when you want to know the latest on a psychological subject. So, give this a try:

Design an imaginary quasi-experimental study. Give us a brief description of your study, then answer as many of the following questions as you care to:

1. What is the hypothesis of your imaginary study?

2. What is/are the independent variable(s)?

3. What is/are the dependent variable(s)?

4.  Briefly, how will you test your hypothesis? That is, what are the procedures you will use in your study?

5. What led you to your hypothesis; that is, what makes you think that changing the independent variable(s) will cause a change in the dependent variable(s)?

6. Now comes the fun question: Why could this study not be conducted with a true-experimental design?

This question is a good one for making sure everyone will have a good understanding of validity in psychological research. What do you see as the relationship between external validity and internal validity?  What steps can a researcher take to strengthen the validity of these different types of studies, a random groups design study, a repeated measures design study, and a complex design? What threats to the validity of these studies’ results must be considered by the researcher?

Martin Seligman founded in the late 1990s a new branch within Counseling Psychology called Positive Psychology. One of the criticisms of this new branch within the psychological community was that while it was strong on theory, there were no interventions associated with it for use in therapy. The article I’m linking for you here was the first to report on research in this area in Positive Psychology.

Positive Psychology has become the most exciting new area of psychology: there are books coming out every month it seems and newspaper and magazine articles about  happiness every week. And they’re all based (or claim to be based) on the research being done by Seligman and others. So, I invite you to read the article and comment on it: what do you think of the quality of the research conducted by the authors? Do you agree that their methodology was valid?

What do you think of internet based studies?

Shaughnessy et al. write, “Self-report measures, often in the form of a questionnaire, are among the most frequently used tools in psychology” (2009, p. 173). Why is this so? What are the pluses and minuses of self-report measures in psychological research? If you were designing a study, would you use self-reporting in your study?

Research based on observational methods historically was associated with educational, sociological, and anthropological research in the behavioral sciences. Only recently has it become more accepted within the psychological community (Patton, 2002). Our text (Shaughnessy, Zechmeister, & Zechmeister, 2009) categorizes observational research into three types: Participant observation, structured observation, and field experiments. There are other ways of categorizing it. That itself gives us a sense of how varied observational research methodologies can be.

Are you an advocate for this type of research within psychology? Is there any particular type of obervational research you like or dislike? Why or why not?
