Answer #1

Which of the following is NOT one of the things that need to exist before we conclude that a causal connection exists between two variables?

- Temporal Order

Other three are not possible because

A nonspurious relationship between two variables is an association, or co-variation, that you cannot explain with a third variable

multicollinearity (also collinearity) is a phenomenon in which one predictor variable in a multiple regression model can be linearly predicted from the others with a substantial degree of accuracy.

Correlation is a mutual relationship or connection between two or more things
