READ THE FOLLOWING SCENARIO TO ANSWER THE NEXT 2 QUESTIONS.  Dr. Sparrow is a social psychologist who studies romantic relationships. Several researchers have found that there is a link between income and marital satisfaction (e.g., Dakin & Wampler, 2008). Dr. Sparrow is curious as to whether there is a causal link between the two variables, such that having a higher income causes higher levels of marital satisfaction. He is confident that he cannot reasonably or ethically manipulate people’s income level. He is also curious as to whether there is a causal link between these two variables or if two other variables (number of arguments and life satisfaction) can explain the relationship. He measures his three variables at one time with a survey in a sample of 124 married couples recruited from a local community center. Below are his results. DV: Marital Satisfaction     Variable Beta (b) Significance (p) Income .69 .03 Number of arguments –.73 .01 Life satisfaction .13 .81

Who is the current (as of the notes, I know things changed a little in the last week) Speaker of the U.S. House of Representatives? 

Before using the measure in her study, Dr. Rodriquez gives the measure to a group of participants on the first day of the semester and again on the last day of the semester. Dr. Rodriquez is examining the scatterplot of the data she collected and notices that the dots are very close to forming a diagonal line. This indicates which of the following?

A correlation-based statistic called  _____________ is commonly used to determine internal reliability.

What is Dr. Michaels’ likely population of interest?

Dr. Guidry realizes that the relationship between number of friends and life satisfaction is only present when both men and women are included in the study. However, the relationship between number of friends and life satisfaction does not exist if women and men are examined separately.  This is likely a(n)

Dr. Gore is conducting a survey examining people’s opinions toward funding for collegiate athletics on his campus. He notices that several participants agree with all 12 questions. This could be an example of all of the following EXCEPT:

The difference between a cluster sample and a multistage sample is:
