Previous research has indicated that alcohol decreases motor coordination, but when alcohol was combined with an energy drink, individuals had _____ feelings of stimulation and increased confidence in their performance, even though their performance was actually worse.

Dr. Watkins held a review session for his statistics class. Dr. Watkins informed the class that there are multiple analyses that can lead to the same conclusion. For instance, a 2 × 3 factorial design would be similar in practice to a combination of a(n):

Dr. Crow is interested in examining the independent variables of ethnicity and receipt of remarks in relation to feelings of social inclusion. The ethnicity variable is represented by Caucasian, African American, and Hispanic American. The receipt of remarks variable includes receipt of compliment, receipt of insult, and receipt of greeting. How would this research study design be noted?

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

In a factorial design W × Y, the Y represents the:

Dr. Henderson identified three independent variables of interest for her current study. Dr. Henderson is examining the relationship among gender identity (male, female, and transgender), birth order (first born, second born, third born), and family context (two-parent or single-parent home). Which type of factorial design does that describe?

Based on previous research, a person's natural scent is complex and contains several compounds, including indicators of MHC and:

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:
