• Provide a formula when the static or mathematical expression is new, rare
or essential to the paper
Formulas
• When reporting inferential statistics (e.g. t tests, F tests, chi-square tests)

Lists
•Heading structure alerts readers to the order of ideas in a paper, seriation
•When a list within a sentence contains three or more items, use a serial
comma before the final item (eg., Participants were similar with respect to
age, gender, and ethnicity)
List Guidelines
•Within a sentence or paragraph narrative, identify elements in a series with
lowercase letters in parentheses when doing so will help readers
understand the separate, parallel items in a complex list.
•Eg., Our sample organisation used a rainfall model that features the
following sequential stages: (a) requirement analysis, (b) specification, (c)
architecture, (d) design, and (e) deployment.
Lettered Lists
•Use numbered list to display complete sentences or paragraphs in a series
•Use a lettered or bulleted list rather than a numbered list if the items are
phrases.
Numbered Lists
•If bulleted list items are complete sentences, begin each sentence with a
capital letter and finish it with a period or other end of punctuation.Bulleted Lists
