Four screw gauges are to be calibrated to the standard thickness tst of a wire. Series of measurements were performed by each instrument to obtain a distribution of the measured values as shown. Which of the following statements is correct?
If the true value for a result is 3.00 m and a student records two readings as 3.01 m and 2.99 m, then we can conclude that:
If the true value for a result is 2.00 g and a student takes 2 measurements and reports the results as 1.95 g and 1.93 g, then we can conclude that:
