When presenting the outcomes of a $t$-test in a research manuscript, specific APA style formatting conventions must be followed. The results are typically written in the format: $t(df) = \text{t-score}, p = \text{p-value}$. For instance, a result might be reported as $t(9) = -3.07, p = .01$. In this structure, the letters $t$ and $p$ must be italicized. The degrees of freedom ($df$) are placed in parentheses immediately following the $t$ symbol, and must be presented as a whole number without any decimal remainder. Finally, both the calculated $t$ score and the $p$-value are rounded to two decimal places.
