The second set: 122, 126, 121, 123.
Reason: accuracy = closeness to accepted value (125). The second set's mean = 123 (close to 125); the first set's mean = 143.5 (far from 125). Precision = consistency (small spread). The second set's standard deviation ≈ 1.9 (tight), the first's ≈ 39.2 (very wide). Thus the second set is both accurate and precise.
