Many applied researchers become ecstatic when their studies produce statistically significant results. Seeing that p < .05, they figuratively jump up in the air and click their heels together, thinking that they have discovered things that are big and important.

Quite often, their joy is totally misguided.

Researchers frequently delude themselves into thinking their studies are noteworthy because they confuse 2 kinds of significance: “statistical significance” and “practical significance.” Had these researchers learned that a result can be statistically significant without having any practical importance whatsoever, they would be better interpreters of their own findings and less likely to mislead others.
