Question

A researcher is interested in the effects of coffee consumption (0, 1, or 2 cups) and TV viewing (0 or 30 mins) on how sociable subjects feel. University students participated in this study, with 20 students randomly assigned to each condition. After watching TV for either 0 or 30 mins, while drinking either 0, 1 or 2 cups of coffee, subjects were asked to rate how sociable they felt on a scale of 1 to 15, where 15 represented the most sociability. The results are as follows:

The results are as follows:

coffee (cups) TV viewing(mins) sociability

0 0 12

1 0 10   

2 0 6

0 30 4

1 30 4

2 30 4

2B) List each significant effect and after each one, describe what the effect is telling us about how coffee and TV viewing affected sociability.

2C) If any of the above effects should take precedence, indicate which effect(s). (If they are of equal importance, simply indicate so.)

2D) What is the name given to this type of design?

Answer 1

2B)

0 0 12 = Coffee and watching has no significant effect on sociability

1 0 10= Coffee has some degree

2 0 6= Coffee shows no significant level in sociability

0 30 4 = Watching TV does not have a major degree of effect in sociability

1 30 4 = No significant change even combined

2 30 4= No significant effect.

2C) Sociability should take precedence than coffee and watching. It should be how sociability influence watching TV and coffee drinking.

2D) Correlational design
