Exam 12: Factorial Designs

Look at the research matrix below without column headings.If you wanted to have 10 participants for each condition, how many participants would you need for a between subjects factorial design? Attractive Attractive Female Male Unattractive Unattractive Female Male

Finding out if each of the independent variables influenced the dependent variable s) is referred to as __________.

Participant sex is always a between subject variable.

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 second independent variable or subject variable in this case) was sex of the researcher in the cover letter.It had _____ levels.

There are three independent variables in a 2 X 3 design.

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

Desrumaux and colleagues conducted a study to determine how evaluating a job applicant varies by the applicant's gender and physical appearance.For the purposes of chapter 10, the authors of the textbook focused on two IVs.From the research matrix below, how many participants would be needed for a mixed subjects factorial design if you wanted to have 10 participants in each condition? Male Male Attractive Unattractive Female Female Attractive Unattractive

A research design in which all independent variables are between subjects is a within subjects facet 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.This quasi-experiment would be referred to as a _____ X ______ research design.

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.Which statement below accurately describes this research design?

In the standard form __________ X __________, what goes in the second blank?

The between subjects factorial design is the preferred design.

Which of the following statements regarding main effects is correct?

A researcher has created a factorial design.She has a between subjects variable and a within subjects variable.What type of design does the researcher have?

You are reading a journal article and the method section states that the design was a 2 X 3 between subjects factorial design.Automatically, you know that the study will have _______ conditions.

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 variable of medical situation is a __________ subjects variable.

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

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.The first independent variable of attractiveness of the researcher was a __________ variable.

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