Question Answered step-by-step Dr. O’Toole thinks spending more time together as a family on… Dr. O’Toole thinks spending more time together as a family on vacation causes children to be happier. He samples 63 families in December of 2008 and measures how many days the family spent on vacation in the past year as well as the child’s happiness. He contacts the same families in December 2013 and measures those two variables again. The results of his study are below. 1. There are three types of correlations discussed in longitudinal designs. From Dr. O’Toole’s study, provide an example of each of the following: a cross-sectional correlation, an autocorrelation, and a cross-lag correlation. Make sure you use the variable names and not just the correlation numbers (e.g., the correlation between 2008 vacation days and 2008 child happiness). 2. There are three possible causal patterns that can be found in a study like Dr. O’Toole’s. Choose one causal pattern and explain which correlations need to be significant, which ones should not be significant, and what type of causal claim can be made. Make sure you use the variable names and not just the correlation numbers (e.g., Correlation 1). Dr. Nguyen is a psychologist who studies legal decision making. He is curious about extra-legal factors – things that are irrelevant to the crime that influence the sentences juries give to defendants. He samples a group of jury-eligible adults, provides them with the facts from a case and allows them to watch the closing statements from the trial. He then asks them to provide a sentence for the defendant. In addition, he measures two legal factors (the number of arguments made by the prosecuting attorney and the length of time the defense attorney speaks during the closing argument) and two extra-legal factors (how attractive the defendant is and how many legal televisions shows the participants watch). Here are Dr. Nguyen’s results.

Choose one variable in Dr. Nguyen’s study and explain how this variable relates to criminal sentencing, considering the direction of the effect, statistical significance, and strength of relationship compared with the other variables. 4. Could Dr. Nguyen conduct an experiment on this topic? Why or why not? Regardless, why would an experiment be better than his current study?
