By averaging three me :b1s(o(bqwws21lhsq0 v,w d aagbn2)q2a5bavrvw q9t;/o 6dasurements of the same quantity which of the following can be re; 2vr9q6aad tvwqb/ 5oduced?
A. Random errors
B. Systematic errors
C. Random & systematic errors
D. Zero errors
参考答案: A
本题详细解析:
Systematic errors arise due to faulty instrumentation or consistently bad t:by97ddcr 8oo: k4ubf echnique. Averaging repeated measurements will not change a systematic bias. So B & C are incorrect. Zero errors are examples of systematic errors, where a the zero of an instrument is not correctly calibrated. So D is incorrect. Random errors will be sometimes too high and at othe:ob8duk9c y fo4d:7brr times too low – so averaging them will have the effect of reducing the random error. Hence A is correct.
