When comparing multiple elements, ensure that the elements being compared are clearly defined to avoid ambiguity. For instance, instead of saying "the results are identical between the groups", specify "the results are identical between the control group and the experimental group".
Common error
Be careful to distinguish between identity and similarity. "Are identical between" means that two things are exactly the same. If there are slight differences, it's more appropriate to use phrases like "are similar between" or "are comparable between".
