Problem 1:
suppose a student measures the time for an air-track glider to travel between two photogates
five times. the results of his measurements are 1.25 s, 1.31 s, 1.23 s, 1.19 s, and 1.27 s. what
value will he report for the measurement?
another way to report the precision of a measurement is the percent relative uncertainty. the
introduction to your lab manual describes how the percent relative uncertainty is calculated.
