    Hello,
    Could you help me about following sentence? Is this sentence grammatically correct? Is the "when" word is used correctly?
    "The obtained results show a modest improvement in the error, when the number of classes is larger than 40."

    Say;

    Could you help me with this sentence?

    I think "when" is used correctly, but the sentence makes no sense. (You can't improve an error.)

    Try The results obtained show a modest reduction in the error rate when the number of classes is greater than 40. I replaced improvement because using that word means you expect your reader to know whether an improvement is an increase or a decrease.
