When referencing years do I need to spell out the numbers if under 10 or for an example can I use 2-6 years?
Which is correct 2-6 years or two-six years?
Answer
To properly use numbers is APA style:
- Use numerals to express numbers 10 and above
- Use words to express numbers below 10
- However, APA does allow for special circumstances. Section 4.31 (c) provides for use of numerals when the number "immediately precedes a unit of measure."
In your example, 2-6 years, years would be considered a unit of measure and so using the numerals is appropriate.
