If a researcher wants to reproduce a previous study, she can do so in multiple ways. A (n) - involves re-creating previous work as closely as possible to the original. Scientists can also conduct a (n) -, in which a study uses different procedures to re-create a similar finding to the original. Finally, a (n) - involves copying the original experiment and including additional variables to answer new questions.
