You can exclude study participants for all of these reasons EXCEPT:

In a research scenario where Red Bull alters the manner in which an individual absorbs alcohol into their systems and influences their overall alertness, which variable is the independent variable?

Based on the following information identify what type of factorial design is being described and how you reached your conclusion: Dr. Dowty is examining the influence of marijuana (daily, weekly, yearly) and food consumption (2000 calories, 3000 calories, or 4000 calories) in examination of metabolism changes over time.

Jessenia wants to conduct a study on how preschool children's social abilities influence their memory for social events. Which of the following settings would be the best for optimizing mundane realism?

Multiple independent variables usually indicate the potential for a(n):

Dr. Johnson described the _____ as the whole being greater than the sum of the parts. It is a helpful reference to understand the combination of two variables to produce an outcome that is bigger than each individual variable contribution.

Delena asked Dr. Whit to repeat his comment about interaction effects with regard to factorial designs. Dr. Whit had stated that it is possible to hypothesize a main effect for one independent variable:

Suppression effect is an effect where two variables _____ to produce an outcome that is _____than what each individual variable contributes.

Dr. Muma wishes to utilize research confederates in his upcoming studies. Which of the following would be the best reason to include a research confederate in an experiment?

In a 3 × 2 × 3 factorial design there are how many independent variables?

______ is when one independent variable's influence on the dependent variable changes depending on the level of the other independent variable(s).

Researchers in a 2009 study assessed whether participants were accurate in their ability to assess romantic interest by having males and females watch short video clips of couples during a date. The video clips depicted German speaking couples. Participants viewed 10s or 30s video clips and either at the beginning, middle, or end of the date. What type of factorial design is this scenario?

Akita is interested in conducting a study examining problem-solving abilities among middle school-aged children. Which of the following settings would be the best for optimizing mundane realism?

An interaction effect hypothesis is a prediction about how the levels of one independent variable combine with another independent to influence the _____in a way that extends beyond the _____of the two separate main effects.

_____ is a statistical test that allows researchers to simultaneously test how two separate nominal or categorical independent variables influence the dependent variable and how those independent variables interact to influence the dependent variable.

In a 5 × 3 × 2 × 2 × 4 × 4 factorial design there are how many independent variables?

How many possible outcomes, including both main effects and interaction effects, are possible for a factorial design with three independent variables?

A 2 × 2 factorial design includes _____ levels in the first independent variable.

In a 2008 study researchers were interested in whether women favored more provocative clothing during more fertile times of the month. Ovulation cycles were mapped, hormonal contraceptives were not used, and the female participants came into the lab twice for urine samples. In addition to being photographed the female participants also completed a diverse array of assessments. The results indicated that:

Dr. Kincaid noted in class this morning while discussing factorial design that sometimes the effects of one independent variable will have a reverse influence across levels of the other variable. This is referred to as a:
