1. Co-variation of X and Y. 2. Temporal order: cause (X) before effect (Y) 3. Absence of alternative causes (confounds/third-variables) In principle, if X is the only factor in a situation that varies prior to a change in Y, then the logical conclusion is that the variation in X must have caused the change in Y.

A crucial step in null hypothesis testing is finding the likelihood of the sample result if the null hypothesis were true. This probability is called the p value. A low p value means that the sample result would be unlikely if the null hypothesis were true and leads to the rejection of the null hypothesis. A high p value means that the sample ...
