Students were asked to measure a string as part of a physics experiment. the actual length of the string was 7.35 cm long. which of the following groups of data show measurements from the most accurate group and why?
7.35 cm, 7.82 cm, 7.12 cm, because one of the measurements is closest to the actual length.
6.95 cm, 6.93 cm, 6.97 cm, because these have the most agreement between the measurements.
7.32 cm, 7.37 cm, 7.39 cm, because this group’s measurements are closest to the actual length. - my answer
7.90 cm, 7.91 cm, 7.89 cm, because these have the most agreement between the measurements.
