The individual predictors were examined further and indicated that age (t = -11.98, p = .002) and gender (t = 2.81, p = .005) were significant predictors in the model. Results of the binary logistic regression indicated that there was a significant association between age, gender, race, and passing the reading exam (2(3) = 69.22, p < .001). The degrees of freedom associated with the test should be in parentheses following the statistical letter or symbol. About APA 7th ed. The other thing to note here is that if your p value is less than .001, it's conventional simply to state p < .001, rather than give the exact value. P-values below .001 are reported as p < .001.
