A handful of papers. Lots more if you include high school and undergrad lab assignments. In my field replication usually involves a lot of guesswork since papers don't usually have enough information to be certain of their exact methods (no code or data unless the planets align or the authors are friendly) and yet peer reviewers happily apply their rubber stamp.
