Critics argue that rejecting a null hypothesis is often uninformative because it only asserts that a relationship is 'nonzero' without describing its actual magnitude. Furthermore, since relationships in the population are rarely exactly zero, rejecting a null hypothesis may simply confirm a fact that was already likely to be true without providing new insight.

According to critics of null hypothesis testing, what is the primary reason that simply rejecting a null hypothesis is often considered uninformative?

A researcher conducts a study and successfully rejects the null hypothesis, concluding that there is a statistically significant relationship between sleep duration and test performance. Based solely on this rejection, the researcher can determine how large or practically important this relationship actually is.
