Expert writing Tips
Best practice
When writing, ensure that the noun modified by the relative clause "that are used" is clear and specific. This improves the clarity of your writing and avoids ambiguity. For example, instead of saying "the methods that are used", specify "the statistical methods that are used".
Common error
Avoid using "which are used" when introducing a defining relative clause, which is essential for identifying the noun. Use "that are used" instead. "Which are used" is more appropriate for non-defining clauses, which add extra information but are not essential to the sentence's meaning.
