Show answer and explanation
Correct answer: (A) 0.12 and 0.14
Explanation
The readings cluster around 0.37 flow units while the true value is 0.25, so bias is approximately 0.12.
The largest reading is 0.39, giving maximum absolute error 0.39−0.25=0.14.
Therefore **A**.
Frequency weighting gives nearly the same rounded central value.
