The measurements made by the group of students using the same balance and a 25.00 gram weight would be precise but not accurate, as they are consistently off by the same amount (evidence of a systematic error). There is no evidence of large random errors, and the data cannot be considered accurate since it is consistently off. Therefore, the best choice is C, which includes options for both systematic errors and lack of accuracy.
