A student measures the diameter of a wire using a micrometer screw gauge and obtains readings of 2.53 mm, 2.55 mm, 2.54 mm, and 2.54 mm. What is the mean diameter of the wire?

Question

Accepted Answer

2.54 mm. The mean diameter is calculated as (2.53 + 2.55 + 2.54 + 2.54) / 4 = 10.16 / 4 = 2.54 mm. Averaging repeated measurements reduces random error and gives the best estimate of the true value.

Answer

A) 2.53 mm

Answer
