Common mistakes
- Do not assume μ, x̄, SD, and SE are interchangeable; use the notation defined by the method or style guide you are following.
- A copied p-value threshold or effect-measure abbreviation is a writing aid, not a statistical conclusion. Add the estimate, interval, units, and method as required.
Word, Docs, Notion, and plain text
Abbreviations and Unicode symbols paste into Word, Google Docs, Notion, and plain text. Use an equation object when accents, stacked fractions, or multi-level indices must remain typographically exact.
