Saying that an effect or difference is significant can be misleading.
In daily life, significant means ‘large’, ‘substantial’ or ‘important’. In the realm of science, however, significant is a statistical term that means something different.
In fact, in science statistically significant outcomes are sometime insignificant from a practical perspective: even a tiny, weak, negligible effect or difference can be statistical significant.
Claims that results were significant often mean that they were statistically significant, which is NOT the same as important or practically relevant.
