Exam 11: Factorial Design: I Lost My Phone Number, Can I Borrow Yours Do Pick-Up Lines Really Work

(Scenario II) Suppose the authors of the study described in Scenario II had categorized children into high-ADHD, low-ADHD, and no-ADHD groups. Children were also categorized has having TD or not having TD. This design can be expressed as:

Tedoro designed a study to examine the influence of social media on self-esteem. In his study he gave participants a social media post (Facebook, Twitter, or Instagram) and a 1-minute video clip (positive, negative, or neutral) to watch. Each participant only receives one level of each IV. Which of the following accurately describes this design?

Main effect hypotheses focus on the effect of _____ independent variable(s) on the _____ variable.

A main effect hypothesis focuses on the effect of _____ independent variable(s) on the _____ variable, ignoring all other independent variables.

A within-subjects factorial design would control for:

(Scenario III) According to Scenario III, there was a main effect for drug consumption, with people receiving the marijuana cigarette with THC being more likely to exhibit risky behavior than those who received the placebo. To arrive at this conclusion, the researchers would have had to examine:

Factorial designs are true experiments where the researchers manipulate the independent variables, all of which are:

Dr. Raqui computed a two-way factorial analysis of variance with types of aggression (relational or overt) and the type of communication method (email, phone, or in-person) as the independent variables, and the level of self-esteem as the dependent variable. The relational aggression main effect was significant, F(1, 222) = 4.2, p = .001, eta² = .031. Which of the following represents the within-subjects degrees of freedom?

Dr. Raqui computed a two-way factorial analysis of variance with types of aggression (relational or overt) and the type of communication method (email, phone, or in-person) as the independent variables, and the level of self-esteem as the dependent variable. The relational aggression main effect was significant, F(1, 222) = 4.2, p = .001, eta² = .031. Which of the following would best represent the factorial design?

(Scenario III) Which of the following accurately describes the design presented in Scenario III?

Ramona wants to conduct a study on how poetry influences students' creativity. Which of the following would be the best for optimizing mundane realism?

Vignettes provide a significant amount of _____ because the researcher can dictate exactly what the participant reads.

Factorial designs have the added benefit of being able to establish:

_____ is any factorial design that has at least one quasi-independent variable.

Which of the following is an example of a third-party introduction?

Dr. Carlson is examining how the consumption of LSD and individuals' body temperatures influences the individuals' interest in physical contact. In this particular research scenario how many independent variables are described?

In a 4 × 3× 3 × 3 factorial experiment, you have _____ independent variables and potentially _____ main effect hypotheses.

A 2002 study involving sex differences in response to physical and social factors in relation to the importance of smell indicated that:

In factorial design, the number of independent variables indicates the number of potential:
