A researcher studied whether there are sex differences in the influence of crowding level (none, low, medium, and high crowding) on stress and rats. Male and female rats were randomly assigned to the crowded cage conditions. Researchers measured cortisol levels at the end of a 30 day period.

This is a...

B. 2 x 4
A researcher studied whether there are sex differences in the influence of crowding level (none, low, medium, and high crowding) on stress and rats. Male and female rats were randomly assigned to the crowded cage conditions. Researchers measured cortisol levels at the end of a 30 day period.

This study includes...
A. a repeated-measures factor
B. a subject variable
C. a single factor with 3 levels
D. three independent variables
B. a subject variable
A researcher studied whether there are sex differences in the influence of crowding level (none, low, medium, and high crowding) on stress and rats. Male and female rats were randomly assigned to the crowded cage conditions. Researchers measured cortisol levels at the end of a 30 day period.

Which of the following is true?
A. this is a single factor, multi-level design
B. this is a multi-level, single factor design
C. this is a factorial design
D. this is a single factor, repeated measures design
C. this is a factorial design
A researcher studied whether there are sex differences in the influence of crowding level (none, low, medium, and high crowding) on stress and rats. Male and female rats were randomly assigned to the crowded cage conditions. Researchers measured cortisol levels at the end of a 30 day period.

Forty rats (20 females, 20 males) were assigned to the low crowding condition. Using the same n in all the cells, how many rats will be needed for the experiment?

A. 140
B. 80
C. 160
D. 20
C. 160
A researcher studied whether there are sex differences in the influence of crowding level (none, low, medium, and high crowding) on stress and rats. Male and female rats were randomly assigned to the crowded cage conditions. Researchers measured cortisol levels at the end of a 30 day period.

Which of the following statements indicates a main effect for sex?

A. males had a significantly higher mean cortisol level compared to females
B. there was no significant difference between mean cortisol levels for males compared to females
C. in females, the most crowded condition cause sig. higher cortisol levels compared to no crowding
D. in males, there was a sig. diff in cortisol levels according to crowding condition
...
