1. Characteristics of students may influence how favorably they are perceived by their teachers. One study examined whether teachers' perceptions of students may be influenced by the student's gender (male, female) and socioeconomic status (SES) (lower class, upper class) (Auwarter & Aruguete, 2008). They had a sample of teachers read a passage about a troubled student; in their passages, the researchers varied the student's gender and SES. After reading the passage, the teacher rated the student on his or her personal characteristics on a 1 to 12 scale; the higher the rating, the more positively the teacher viewed the student. The researchers hypothesized that male students would be rated more highly if they were of upper than lower SES, but the reverse were true for female students.

a. State your hypotheses pertaining to main effects only in statistical forms. State your hypothesis pertaining to an interaction effect in words. (3)

Main effect of.......

Main effect of...

Interaction....

b. If the interaction effect is significant, usinga = .01, conduct tests of simple effects of SES at each level of the gender of students see if the researcher's hypothesis is supported (3).

Note: For #1 Don't just do words also do statistical form.
