Expert writing Tips
Best practice
When using the phrase "a population which", ensure the relative clause that follows provides essential information that defines or limits the scope of the population being discussed. Without the relative clause, the meaning might be too broad or ambiguous.
Common error
Avoid substituting "which" with "that" when using nonrestrictive clauses. "Which" is typically used to introduce nonrestrictive clauses, providing additional but nonessential information about the population. Using "that" incorrectly can alter the intended meaning and make the sentence grammatically awkward.
