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

Use the following to answer questions Scenario II Scenario II is presents fabricated data inspired by the following study: Greimel, E., Wanderer, S., Rothenberger, A., Herpertz-Dahlman, B., Konrad, K. & Roessner, V. (2011). Attentional performance in children and adolescents with tic disorder and co-occurring attention-deficit/hyperactivity disorder: new insights from a 2×2 factorial design study. Journal of Abnormal Child Psychology, 39, 819-828. Effect of Tic Disorder and ADHD on Children's Attention This study examined the extent to which tic disorder (TD) and attention-deficit/hyperactivity disorder (ADHD), both individually and combined, affects attention in children and adolescents. To that end, the researchers recruited children with and without TD, and children with and without ADHD. This 2 × 2 (TD × ADHD) design resulted in four conditions: children with no diagnosis (control), children with TD only, children with ADHD only, and children with TD+ADHD. The Child Behavior Checklist (CBCL) was used to quantify three components of attentional behavior: internalizing, externalizing, and attention. The results revealed that children with ADHD+TD had significantly more internalizing than those with TD alone. In addition, children with ADHD+TD as well as children with only ADHD had more externalizing than those with TD alone. Lastly, ADHD+TD children had more attention problems than those with only TD and those with only ADHD. The results of this study suggest that children with ADHD+TD have more behavioral problems than those with single diagnoses and those with no diagnoses. -(Scenario II) Which of the following may have been the results of the ANOVA performed by the authors of Scenario II?

Rick is conducting a two-way analysis of variance for his research methods term paper. He plans to simultaneously test how two separate _____________ independent variables influence the __________ variable and how those independent variables interact to influence the dependent variable.

In a factorial design, the number of independent variables indicates the number of potential main effect hypotheses, and there are as many interaction effect hypotheses as:

If any one of the independent variables in a factorial design uses a _____ format, the factorial design becomes a mixed design.

In a 2 × 2 factorial design using a within-subjects design:

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

A 2003 study investigating complex genes and body scent attractiveness in men and women found that:

_____ is a description of a hypothetical situation, event, or scenario to which participants react.

Synergistic effect is an effect where two variables ____ to produce an outcome that is _____ than what each individual variable contributes.

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 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 effect size?

A hybrid design occurs when at least one of the independent variables is a quasi-independent variable and is unable to be:

In a 2003 study looking at histocompatibility complex genes, symmetry and body scent attractiveness in men and women researchers asked 200 males and females to provide a blood sample to assess their major histocompatibility complex (MHC) gene, then to sleep a new clean T-shirt for two nights. Researchers also took photos of the males and females to document left- and right-side body symmetry. When the participants were asked about attractiveness, their answers indicated that the:

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 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?

What is a marginal mean?

Cindy asked Dr. Carisle to repeat her comment about interaction effects with regard to factorial design. Dr. Carisle had stated that it is possible to hypothesize interactions without predicting:

______ refers to the average of all participants on one level of the independent variable, ignoring the other independent variable.

Describe at least two benefits of factorial designs.

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 combination. Which of the following accurately describes this design?

A 2007 study examining the scent of male sweat in relation to cortisol levels in women found that:

Write a main effect hypothesis and an interaction effect hypothesis.
