Prior to that work, there had been no attempt to introduce error bar calculations into sampling.

A clock with an accuracy of one in a million will introduce an error of one millionth of a second each second.

Starting with too small an initial step size can potentially introduce error into the final solution.

Language necessarily complicates and introduces error into the pure realm of form.

To maintain the integrity of the laboratory process, the medical laboratory scientist recognizes factors that could introduce error and rejects contaminated or sub-standard specimens, as well as investigates discrepant results.
