Question:
Can a result be described as statistically significant but not practically significant?



Replies:
"Statistical significance" is a term that refers to some statistical criterion, usually the numerical value of some formula or calculation. "Practical significance" I assume means its utility, and that is in the eyes of the beholder. What may be impractical to you or me may be very practical to a mathematician or theoretical physicist.
