Avoid tendencies to make words longer than necessary, i.e., universalizable, suicidality, generalizability. Use italics, boldface, dashes, and parentheses sparingly. In the reports of statistical results, F, Chi-square, t values, and probability levels are rarely sufficient, particularly if statistically significant. It is almost never necessary to have more than three digits after the decimal point. Numbers should therefore be rounded to three or fewer decimals.
Greater precision is usually illusory.
Only in rare circumstances should a significance level be shown as less than .001. If the output says zero or less than .001, report it as equal to or less than .001. Equations should be clearly marked. Superscripts and subscripts should be typed as such. The same applies for superscripts, the most common of which is r 2.
