The correlation between two variables X and Y is -1, the correlation is significant. This suggests that The correlation between two variables X and Y is -1, the correlation is significant. This suggests that For each unit decrease in X we would expect Y to increase by a unit For each unit decrease in X we would expect Y to decrease by a unit For each unit increase in X we would expect Y to increase by 1 a unit For each unit increase in X we would expect Y to decrease by 1 a unit The two variables are not correlated
