When the diameter of a wire is measured with a screw gauge, the following readings are obtained - 1.328, 1.330, 1.325, 1...

A student makes measurements of the diameter of a wire with the help a screw gauge and he gets the following readings : 0.38, 0.40, 0.39, 0.37, 0.41, 0.40, 0.38, 0.39, 0.40 and 0.41 mm. Calculate the average error and standard deviation of his measurements.

The diameter of a wire as measured by a Screw gauge was found to be 1.328, 1.330, 1.325, 1.326, 1.334 and 1.336 cm. Calculate (i) mean value of diameter (ii) absolute error in each measurement (iii) mean absolute error (iv) fractional error (v) percentage error. Also, express the result in term of absolute error and percentage error.

the diameter of a wire was measured as 1.65 mm with a certain faulty screw gauge when the correct diameter was 1.60 mm. what type of error does the faulty screw gauge have?

The diameter of a wire is measured with a screw gauge having least count 0.01 mm . Out of the following the one which correctly expresses its diameter is

The diameter of a wire as measured by a screw gauge was found to be 1.002cm, 1.004cm and 1.006cm . The absoulue error in the third reading is

The diameter of a wire as measured by a screw gauge was found to be 1.002cm, 1.000cm and 1.006cm . The absoulue error in the first reading.

The diameter of a wire is measured by using a screw gauge having least count 0.01mm . If the diameter is found to be 0.20mm , then the error in the cross-section of the wire will be

While measuring diameter of a wire using a screw gauge the main scale reading is 7mm and zero of circular scale is 35 divisions above the reference line. If the screw gauge has a zero error of -0.003cm , the correct diameter of the wire is (given least count =0.001cm )
