When presenting the outcomes of a t-test in APA style, to how many decimal places should both the calculated t score and the p-value typically be rounded?

A psychology student reports the following t-test result in a research paper: t(14.00) = 2.45, p = .03. This is correctly formatted because all numerical values have been consistently rounded to two decimal places.

A psychology researcher conducts a study and obtains the following results: degrees of freedom = 12.0, t-statistic = 2.126, and p-value = 0.054. Arrange the following components in the correct order to construct the APA-style reporting string for these results.

A psychology researcher is auditing a research manuscript and finds several formatting errors in the statistical results. Match each incorrectly formatted reporting string to the specific APA rule it violates.

You are designing an automated reporting tool for a psychology lab that must synthesize raw statistical output into a perfectly formatted APA-style reporting string for research manuscripts. If the tool receives raw data from a study with 16 participants ($df = 15$), a calculated $t$-score of $2.4$ (exact), and a significance level of $0.038$, which of the following output configurations should you program the tool to generate?

A researcher argues that reporting a result as $t(12) = 2.1, p = .04$ is preferable to writing $2.10$ because their calculation was exact and required no rounding. When evaluating this claim against the APA style standard for decimal precision, the researcher's reporting of the $t$-score is incorrect and must instead be written as _____.

According to APA style formatting conventions, when reporting the results of a $t$-test, the letters $t$ and $p$ must be italicized, and the degrees of freedom ($df$) must be written as a whole number without any decimal remainder.

A researcher conducts a study and obtains the following results: degrees of freedom = 14.0, calculated $t$-statistic = -3.482, and $p$-value = 0.007. Match each raw value to its correctly formatted APA style representation.

A student reports their $t$-test results in a manuscript draft as follows: $t(19.0) = 2.84, p = .03$. To correct the formatting error in the degrees of freedom according to APA style guidelines, the value inside the parentheses must be written as _____.
