An objective summary should include key points and essential information from the text, presented in a neutral manner. If "statistical data from the text" accurately reflects important elements of the text's content, this could be included in an objective summary. However, if there were no additional responses or context provided, it's essential to ensure that whatever is included is relevant, unbiased, and serves the purpose of succinctly conveying the main ideas of the original text.
So, in this case, including statistical data could be appropriate for an objective summary, assuming that is part of the text's key information.
