In research, replication is the process of repeating a study in order to obtain the same or similar results. If a claim is thought to reveal a regularity about the world, then it is inevitably generalizing to situations that have not yet been observed. Replication can occur in observational research when the conditions presumed essential for observing the evidence recur, such as when a new seismic event has the characteristics deemed necessary and sufficient to observe an outcome predicted by a prior theory or when a new method for reassessing a fossil offers an independent test of existing claims about that fossil. With no revisions for the cultural context? The Two Rs in Science Research: Repetition and Replication - The learning objectives of this lesson are that the students will demonstrate that replication is the ability to make an exact copy, explain the importance of writing and following precise directions and differentiate replication by others and repetition (multiple trials) and its importance in science.

To confirm results or hypotheses by a repetition procedure is at the basis of any scientific conception. The theoretical understanding evolved, and subsequent replications supported the revised claims. The operators set the factors at predetermined levels, run production, and measure the quality of five products. Once we have repeated our testing over and over, and think we understand the results, then it is time for replication. For example, if you find that listening to audio programs helps you stay motivated, make sure to listen to them on a daily basis. No, replication and repetition are not the same thing. Because replication is defined based on theoretical expectations, not everyone will agree that one study is a replication of another.

For example, the claims that there are more obese people in wealthier countries compared with poorer countries on average and that people in wealthier countries live longer than people in poorer countries on average could both be highly replicable. This whiteboard activity is used to engage students in learning the difference between repetition and replication. Deciding whether studies are replications after observing the outcomes can leverage post hoc reasoning biases to dismiss failures as nonreplications and successes as diagnostic tests of the claims, or the reverse if the observer wishes to discredit the claims. If we did miss something, it is OK, as long as we performed our tests honestly and scientifically. Repetition is important for a number of reasons. Yes Repetition is multiple trials, when replication is when you redo the entire experiment.

To be a replication, 2 things must be true: outcomes consistent with a prior claim would increase confidence in the claim, and outcomes inconsistent with a prior claim would decrease confidence in the claim. The ambiguity between disconfirming an original claim or identifying a boundary condition also means that understanding whether or not a study is a replication can change due to accumulation of knowledge. copies another scientist's experiment. Meaning of repetition. Required fields are marked *. Yes, it should, so if we repeat the experiment and get a different result, then we know that there is something about the test that we are not considering.
