Question 9
An analog voltmeter has 100 divisions on the scale. The voltage read is 6 volts and the
meter has two ranges as 0 – 10 volts and 0-100 volts. Find the uncertainty in the
measured value in both ranges. (Uncertainty = ±½ VFSD / # of divisions)
Question 10
The following values obtained from the measurements of the values of
147.2,147.4,4,147.9,148.1,147.7,147.5,147.6,147.4,147.6 and 147.5.
Calculate:
The arithmetic mean
The standard deviation
