In an experiment, the coefficient of viscosity (in mPa s) of a liquid was determined as 2.62, 2.68, 2.58, 2.57, 2.54 and 2.55. The mean absolute error in the determination of the coefficient of viscosity of the liquid is
- A 0.08 mPa s
- B 0.12 mPa s
- C 0.06 mPa s
- D 0.04 mPa s
Answer & Solution
Correct Answer
(D) 0.04 mPa s
Step-by-step Solution
Detailed explanation
\(\bar{\eta} = \frac{2.62 + 2.68 + 2.58 + 2.57 + 2.54 + 2.55}{6} = 2.59\) \(\overline{|\Delta\eta|} = \frac{|2.62-2.59| + |2.68-2.59| + |2.58-2.59| + |2.57-2.59| + |2.54-2.59| + |2.55-2.59|}{6}\)…
