Read the following text that describes an analytical study and complete the table below it: This research investigated the association or the relationship between some factors, namely (1) type of cars, (2) age and (3) gender of the car drivers and car accidents. More specifically, the researcher wanted to find out if these three independent factors had an impact on car accidents. He hypothesized that "car accidents do not increase or decrease as a result of the age of the drivers, gender of the driver and type of car". The sample of this research consisted of 2000 car drivers of different gender, ages and types of cars. The researcher designed a questionnaire to collect the primary data required. The questionnaire was very short. It elicited some demographic data from the respondents such as their gender, their age, and the type of car they used. The questionnaire also elicited from the participants if they had had accidents, the number of accidents they had and at what age they had…
For each of the following epidemiological scenarios, draw a DAG that represents the relationships between the variables: A researcher is studying the association between experiencing childhood abuse (A) and the occurrence of depression (D) as an adult. She has reason to believe that alcohol consumption (C) may mediate the relationship between (A) and (D).

Correlation studies are often used to help determine whether certain characteristics are controlled more by genetic influences or by environmental influences. These studies often examine adopted children and compare their behaviors with the behaviors of their birth parents and their adoptive parents. One study examined how much time individuals spend watching TV (Plomin, Corley, DeFries, & Fulker, 1990). The following data are similar to the results obtained in the study. a. Compute the correlation between the children and their birth parents. b. Compute the correlation between the children and their adoptive parents. c. Based on the two correlations, does TV watching appear to be inherited from the birth parents or is it learned from the adoptive parents?
Dr. Morgendorffer wants to develop a questionnaire that measures employees' burnout. But during her literature review, she learns that burnout is a variable with three separate dimensions: exhaustion, cynicism, and detachment. Which of the following checks will help ensure that Dr. Morgendorffer's burnout questionnaire is valid? O a. Ensuring that the items across all three dimensions are correlated with each other O b. Ensuring that there is a high level of stability for each of the three dimensions OC. Ensuring that the dimensions represent parallel forms of the questionnaire O d. Ensuring that all three dimensions have been adequately represented in the questionnaire
Apperson and Fitz is a chain of clothing stores that caters to high school and college students. It publishes a quarterly catalog and operates a Web site that features provocatively attired males and females. The Web site is very expensive to maintain, and company executives are not sure whether the number of hits at the site relate to sales (i.e., people may be looking at the site’s pictures only). The Web master has accumulated the following data for hits per month and orders placed at the Web site for the past 20 months: Develop a linear regression model for these data and indicate whether there appears to be a strong relationship between Web site hits and orders. What would be the forecast for orders with 50,000 hits per month?
