Statistical means based on the study of collected numbers. Statistical analysis, a statistical error, statistical significance.
Statistical significance is the phrase that carries the most weight and the most misunderstanding, since it says a result is unlikely to be chance rather than that it is important. A statistical model is a set of assumptions about how numbers were produced.
