Chance errors are errors related to the variability in repeated measurements and change from measurement to measurement, sometimes up and sometimes down.True or false: If we increase the number of measurements taken, the long-run average of repeated measurements should give the exact value of the thing being measured. True: Chance errors and bias can both be reduced by increasing the number of measurements taken.  True: Assuming there is no bias in the measurement procedure, the chance errors should cancel out. False: Chance errors can only be reduced by carefully selecting the measurements that are not outliers.  False: Chance errors are inevitable and cannot be reduced no matter how many samples are taken.
