Replication is an essential part of the scientific process, but replicable research has been more of an assumption than a practice. Over the last few years a number of high profile replicability projects have raised questioned about the replicability of research in a variety of disciplines and brought the practice of replication to the forefront of scientific discourse. But how do researchers decide what kind of replication to do and what are the steps needed to conduct a replication? This chapter briefly summarizes different types of replications and the different ways they contribute to scientific knowledge. Step-by-step guidance for researchers looking to conduct replications is described, as well as a discussion of how to interpret results and new options for publishing replications.
