Best practice
When using "less than 1" in scientific or statistical contexts, ensure the units of measurement are clearly defined. For example, "The p-value is less than 0.05" is more precise than "The p-value is less than 1".
Common error
Avoid stating that something is "less than 1%" when you mean it's simply "less than 1". A percentage already implies a fraction of 100, so specifying "less than 1%" means it's an even smaller fraction, not just any value below one.
