Is there a relationship between mediation activity and cooperation between two nations in conflict? A data set was assembled across 15 time periods. Both variables were measured on an interval scale ranging from 1 (low activity/cooperation) to 5 (high activity/cooperation).

Mediator activity (IV): 1  1  1  2  3  4  2  1  3  2  1  4  5  4  3

Cooperation (DV):      1  1  2  1  3  3  1  2  4  3  2  4  4  5  4

a)   Can cooperation be predicted from the level of mediator activity?

b)    Is there a relationship between these variables?

c)    What do you conclude from these results?

d)   What happens if we add another independent variable, internal policy shifts within one of the nations? This is also measured on a scale that ranges from 1 (no shifts) to 5 (many shifts in a peaceful direction).

Policy shifts (IV2):      4  4  3  1  2  3  3  4  5  5  4  4  3  4  5

e)  What do you conclude from this analysis? Which is the stronger IV?
