A t-test, for example, is reported in the following format: t (18) = 3.57, p < .001, where 18 is the number of degrees of freedom (N - 2 for an independent-groups t test).

The results section should be in condensed format and lacking interpretation. Here are three suggestions to make it just a little easier. Which paths are not "important" to the model - the only part that is statistically tested . A large effect size means that a research finding has practical significance, while a small effect size indicates limited practical applications.
