Question 4

In a 3x3 factorial design, how many different F ratios will be calculated in the ANOVA?

Accepted Answer

A) 2 
B) 4 
C) 9 
D) 3
The next four questions refer to the following experiment:
A researcher investigated the effect of a child's attractiveness and gender on judgments of personality and intelligence. Male teachers were shown photos of children to obtain their "first impressions" of children. Each teacher was shown four photos (the order was randomized for each teacher): an attractive boy, an unattractive boy, an attractive girl, and an unattractive girl. The teachers rated the apparent friendliness of the child and also estimated the child's intelligence.
