Question and opinion

Dr.Ying Ling  Post i.1

Elizabeth,

Very interesting topic here. T test, and multiple regressions might be appropriate for your study.  Would you please explain what might be the measures for environment as well as lifestyle?

Re:Module 1 DQ 2

In reviewing chapter 2, how much did you recognize and understand from your PSY-845 class? What are some elements that are still confusing to you? Try to be specific as this will help you plan your work approach for this class.

I feel good about the idea that the sample should represent the population and that we are looking for statistical significance.  I am also recalling the types of variables: dependent and independent, and also whether they are quantitative (basically a number), or qualitative (non-metric).  I think I am also good when it comes to measures of scales. 

However, once you get into concepts of covariates, it gets more complicated, which is why this class can seem intimating. The ice cream and crime rate correlation example provided in our text (Meyer, Gamst, &  Guarino, 2014) was a good reminder about the importance of getting the right context, and considering confounding variables (temperature) when determining statistical significance.  The deeper aspects of statistical significance including t tests, f tests, z scores, alpha levels, and Pearson correlations are all items that I will need to have my book and reference material on hand for as I step through them. I don’t think that will ever change. At this point in time I am entirely lost when it comes to eta square, phi square, chi square, and Cramer’s V. I am also very nervous about my lacking skills with using SPSS.
