Exam 15: The Logic of Multivariate Analysis

In conducting a project to study the relationship between number of criminal offenses committed and education, a researcher introduces the variable of age. When this was done, the relationship between education and crime disappeared. What type of research was conducted?

The acceptance of a hypothesis is really a function of the extent to which it has been tested and not disconfirmed.

Caitlin studied the relationship between gender and adjustment to retirement. She controlled for type of job before retirement and set up tables relating gender to retirement adjustment for each of her three categories of job type before retirement. The relationships displayed in these tables are known as:

Professor Smith found a relationship between education and occupation. However, when age was introduced as a test factor, the relationship between education and occupation disappeared in the partials. In Professor Smith's study, age was introduced as a(n):

The key to making ex post facto hypothesizing legitimate is that:

The relationship between IQ and shoe size, with no other variables measured, is an example of a(n):

Forrester found a strong positive relationship between participation in high school extracurricular activities and community involvement as adults. He controlled for amount of college and the relationship between high school extracurricular activities and community involvement was nonexistent for all three categories of college attainment. Which type of elaboration analysis is this?

Interpretation only differs from explanation when it comes to the level of measurement used.

The elaboration model examines the impact of other variables on the:

A relationship was found between education and income. Tables A and B are the partials controlling for sex. What do these tables indicate? ​ ​

Good researchers always avoid ex post facto hypothesizing.

Naoko performed a research project on community perceptions of police officer discretion, and after observing the empirical relationship, she created a hypothesis that explained the relationship between the variables. She engaged in:

Forrester found a strong positive relationship between participation in high school extracurricular activities and community involvement as adults. He controlled for amount of college and the relationship between high school extracurricular activities and community involvement was negative for low college attainment, nonexistent for medium college attainment, and positive for high college attainment. Which type of elaboration analysis is this?

The variable held constant in the elaboration model to determine the relationship between others is a(n):

Walter discovered a strong positive relationship between parental engagement with their children and subsequent college success. He controlled for the educational level of parents and found the same relationship in all three partial tables for parental education level. Which type of elaboration analysis did he perform?

Forrester found a strong positive relationship between participation in high school extracurricular activities and community involvement as adults. He controlled for gender and the relationship between high school extracurricular activities and community involvement was nonexistent for both men and women. Which type of elaboration analysis is this?

The particular value of the elaboration model is to show

Stephen found a strong positive relationship between participation in high school extracurricular activities and community involvement as adults. He controlled for gender and got the same relationship between high school extracurricular activities and community involvement for both partial tables showing men and women. Which type of elaboration analysis is this?

Ex post facto hypothesizing refers to the development of hypotheses "predicting" relationships that have already been observed in the data.

To begin the elaboration paradigm, we must know whether the test variable
