Listing Numbers In An Essay

by Timothy McAdoo

This is the fourth in a six-part series. Today we’ll look at numbered lists.

Numbered Lists

Numbered lists (as noted on p. 64 of the Publication Manual of the American Psychological Association) can be used to denote items in a series, such as conclusions or procedural steps. By virtue of their formatting, numbered lists stand out from the regular text and are more likely to catch a reader’s attention. So, be sure to use the numbered list format only when the list format will add clarity to the text.

Numbered lists can be useful to show the relationship between items: a chronology of events, each item’s relative importance, and so on.

The items can be single sentences or full paragraphs. In either case, the first words of the sentences are capitalized and appropriate end punctuation should be included.

Each task increased in difficulty.
1. The instructor read the rules, which began on page 2 of the booklet.
    The wording of these rules differed significantly for each group (see
    Appendix A).
2. The instructor asked if there were any questions.
3. After any questions had been answered, the instructor started
    the timer and told the participants to begin.

If the items on the list are not complex and the list itself does not warrant special attention, consider running the items into regular text. See Parts 2 and 3 of this series for more detail on the use of serial commas, semicolons, and lowercase letters.

More to Come

In Part 5 of this series, I’ll cover a list format new to APA Style with the 6th edition: bulleted lists!

Although usage varies, most people spell out numbers that can be expressed in one or two words and use figures for numbers that are three or more words long. Note: If you are using a specific citation style, such as MLA or APA, consult the style manual for specific formatting instructions.
