Course Discussion Questions
DQs listed below are available from the website for $3 each. If you need a DQ not listed contact the website at least 3 days in advance with the DQ you need and the website will do an original DQ for you for $5.
WK 1 DQ 1: As we begin our venture into statistics, let's pause to examine the role of research in psychology. Psychology is the science of behavior. We think of psychology as counseling, introspection, learning, cognition, etc. How can these processes be the subject of research? How do we reconcile the discipline and rigor of good research with the ambiguity of human emotions and motivations? What is the role of research in psychology?

WK 1 DQ 2: Many people feel nervous around math, but what we really need to fear is the selective interpretation of data! For most of us, 1 + 1 = 2, but in the hands of some, 1 + 1 can be "spun" to support specific agenda. Think about commercials or news clips that you may have seen recently. In what subtle ways might data have been used to influence the listener/viewer? For example, when we hear, "Four out of five dentists recommend Glittering Grin toothpaste!" is it correct to assume that 100 dentists were polled and 80 voted for Glittering Grin?

WK 2 DQ 1: More and more, we are asked to document impact and to measure outcomes. We are asked to provide information about a variety of things through as many varieties of ways. When we go to stores and they ask us for a zip code or phone number. The list could go on and on. You text talks about descriptive statistics and suggests that they are used to make a group of numbers understandable in a research study. While that is certainly the case, we use descriptive statistics in a number of other ways.
Can you think of ways that you might use descriptive statistics at work or in your personal life? 
WK 2 DQ 2: Research in the library a journal article that is in your area of interest in which reliability and validity data are reported. Discuss the outcome measures that are used. Identify the type of reliability that was established and the type of validity. Comment on whether you think the levels are acceptable. If not, how can they be improved?

WK 3 DQ 1: Please read the following article in your Electronic Readings, Null Hypothesis,
CLOSED THINKING: Without scientific competition and open debate, much psychology research goes nowhere This article discusses research in psychology and how "science often works more like a fashion" (Bower, 2013). What does this article tell you? Your thoughts? It is also suggested that significance tests should be banned for two reasons, (1) that there is a tendency for researchers to accept the null hypothesis as true because the result is not significant and (2) significance is confused with a large effect size. Would you agree that testing the significance of a result may lead to faulty assumptions about accepting the null hypothesis? Bower, B. (2013). Closed thinking: Without scientific competition and open debate, much psychology research goes nowhere.Science News, 183(11), 26. 
WK 3 DQ 2: It is suggested that significance tests should be banned for two reasons, (1) that there is a tendency for researchers to accept the null hypothesis as true because the result is not significant and (2) significance is confused with a large effect size.
Would you agree that testing the significance of a result may lead to faulty assumptions about accepting the null hypothesis? 
WK 4 DQ 1: What is a research question each of you would like to research?
· What are independent and dependent variables? · What would your hypothesis be? · Using the decision tree on page 255 of Statistics for People Who (think they) Hate Statistics as a resource, identify which statistical test you would use to test your hypothesis. · Tell us why you selected that particular test. 
WK 4 DQ 2: Let's take some time this week and look at some data that is used to make up reports through the Anne E. Casey Foundation. The Foundation published a document called Kid's Count which is a collection of significant information about risk factors for kids. Please go to the Foundation's website at www.aecf.org, find the information for your state, review some of the key data, tell us what you might use the data for and what are some of the problems with the data, especially as you look at census data atwww.census.gov Datafinder, in comparison to kids' count data.

WK 5 DQ 1: Thomas Bayes who was an English Clergyman in the early 18th century who is known for the Bayes' Theorem. The theorem suggests that science is about conducting research in order to adjust our preexisting beliefs in light of the evidence collected. Conclusions drawn from an experiment are always in the context of what we believed about the world before the experiment.
Others suggest that it is better not to make any assumptions about prior beliefs. (Aron, Aron & Coups, 2006) Where do you weigh in on this debate? Do you think we do research in order to validate something we already believe to be true or false? 
WK 5 DQ 2: When two variables are correlated, it means that they are associated with one another. But if they are associated with one another, then why doesn't one cause the other?

WK 6 DQ 1: We have looked at a number of important statistical concepts over the past few weeks and there is value in considering how some of those concepts are employed to drive decisions that impact all of us and our families.
Actuarial Science uses math and statistics concepts to provide information that drives life insurance and medical insurance policy and procedures. In health insurance, actuarial science focuses on an analysis of rates of a number of different areas. Professionals in this area also use something called "catastrophic modeling" that uses a computer model to estimate the level of damage and exposure that an insurance company might have in the event of a catastrophic event, such as a hurricane.
Please take a look at http://encyclopedia.thefreedictionary.com/Catastrophe+modeling How do you think events such as Hurricane Sandy impact this work and the results? Could someone have "modeled" what happened in New York and New Jersey and the damages to people and property?
