Exam 12: Factorial Designs

In the following phrase, the number 3 represents the levels of the first independent variable: 2 X 3 design.

Desrumaux and colleagues conducted a study to determine how evaluating a job applicant varies by the applicant's gender and physical appearance.The first independent variable was the applicant's gender and the second independent variable was physical appearance.When the researchers look for a main effect of A, which independent variable will be examined?

Look at the research matrix below without column headings.What type of design does this research matrix represent? Attractive Attractive Female Male Unattractive Unattractive Female Male

Participant sex is always a within subjects variable.

A __________ subjects factorial research design is a research design in which all independent variables are within subjects.

In the following phrase, the number 2 represents the levels of the second independent variable: 2 X 3 design.

In the following phrase, the number 3 represents the levels of the second independent variable: 2 X 3 design.

A recent study by Dommeyer 2008) examined what factors influence whether or not people respond to a mail survey.In other words, are there factors that can influence if a person responds to a survey that he or she received in the mail? Dommeyer wanted to know if the attractiveness of the researcher attractive and not attractive) in a cover letter would influence if people responded to the mail survey.Dommeyer also wanted to know if the sex of the researcher male or female) in the cover letter would influence if people responded to the mail survey.So, participants viewed 1 of 4 mail surveys.This quasi-experiment would be referred to as ________ design.

A recent study by Dommeyer 2008) examined what factors influence whether or not people respond to a mail survey.In other words, are there factors that can influence if a person responds to a survey that he or she received in the mail? Dommeyer wanted to know if the attractiveness of the researcher attractive and not attractive) in a cover letter would influence if people responded to the mail survey.Dommeyer also wanted to know if the sex of the researcher male or female) in the cover letter would influence if people responded to the mail survey.The first independent variable was attractiveness of the researcher in the cover letter.This independent variable had _____ levels.

What does the 3 stand for in a 3 X 2 design?

A research design in which all of the independent variables are not the same type is a mixed subjects facet design.

Which of the following statements is true regarding factorial research designs?

There are two standard types of factorial designs.

Researchers Brescoll and Uhlmann 2008) wanted to know if men and women were judged the same for expressing similar emotions in the workplace.Participants in this experiment watched a video of a job candidate.The job candidates were being interviewed while sitting at a table.The job candidates were describing an incident in which they and a colleague lost an important account and how it made them feel.The first independent variable was sex of job candidate.Sex had two levels-male and female.The second independent variable was emotion displayed.Emotion displayed had two levels-anger and sadness.So, participants viewed one of four job candidates.In this study, the second independent variable of emotions displayed was a __________ subjects variable.

Interactions occur when the effect of one independent variable depends on another independent variable.

A research design in which all dependent variables are within subjects is a within subjects factorial design.

Desrumaux and colleagues conducted a study to determine how evaluating a job applicant varies by the applicant's gender and physical appearance.The first independent variable was the applicant's gender and the second independent variable was physical appearance.When the researchers look for a main effect of B, which independent variable will be examined?

In the following phrase, the number 2 represents the levels of the first independent variable: 2 X 3 design.

Catz and colleagues conducted an experiment with 207 individuals taking HIV medications.Participants were randomly assigned to read one of six vignettes.The vignettes varied by medical situation and physician prescription action.For medical situation, participants were randomly assigned to one of three levels.For physician prescription action, participants were randomly assigned to one of two conditions.In this example, the factorial design would be represented as:

A research design in which all independent variables are between subjects is a between subjects facet design.
