Therefore, declaring that a study is a replication is a theoretical commitment. As with repetition, the most important things to watch for are results that dont fit our hypothesis, and for the same reason. In fact, conducting a replication of a prior claim with a different methodology can be considered a milestone for theoretical and methodological maturity. When you measure something once, the chance that the number you get is accurate is much lower. endobj Whats the difference between a repeated experiment and a replicated experiment?

Ecologist Rebecca Means discusses the use of statistical sampling and comparative studies in field biology. Repetition is multiple trials, when replication is when you redo the entire experiment. This resource is a teacher led reading which will introduce the students to the Scientific Method Concepts of Replication and Repetition. Much later, after his and others failures-to-replicate his original claim, a crucial theoretical insight identified that the time of year at which Loewi performed his experiment was critical to its success [13]. C. Repetition occurs when multiple sets of measurements are made during one scientific investigation. Page 3 is the Lab Directions, Answer Key. Accounting & Finance; Business, Companies and Organisation, Activity; Case Studies; Economy & Economics; Marketing and Markets; People in Business In each experiment, five measurements are taken at each combination of factor settings. 1 1 Differentiate replication (by others) from repetition (multiple trials). students were able to complete in about <15 minutes. Sometimes the result might be due to some variable that you have not recognized. Repetition and replication ensures that experiments and experimental results are valid. Whether you use repeats or replicates depends on the sources of variability you want to explore and your resource constraints. Jens Foelldiscusses how statistical noise reduction is used in fMRIbrain imaging to be able to determine which specifics parts of the brain are related to certain activities and how this relates to patients that suffer from phantom limb pain. In scientific research, replication is essential in order to confirm that results are accurate and not just a fluke. The theoretical understanding evolved, and subsequent replications supported the revised claims. This is a useful research activity for advancing understanding, but many studies with this label are not replications by our definition. The purpose of replication is to advance theory by confronting existing understanding with new evidence.

D: Scientific knowledge is based on observation and inference; it is important to recognize that these are very different things. Ironically, the value of replication may be strongest when existing understanding is weakest. Because there is no exact replication, every replication test assesses generalizability to the new studys unique conditions. Repetition requires the experiment to be repeated at least three times and replication requires the experiment to be conducted by another researcher. Dang T.C.T., Strong B.

There are two versions of the activity- one with 2 or one with 3 cups, depending on how much time you have or materials you need to purchase. What had been perceived as replications were not anymore because new evidence demonstrated that they were not studying the same thing. To repeat an experiment, under the same conditions, allows you to (a) estimate the variability of the results (how close to each other they are) and (b) to increase the accuracy of the estimate (assuming that no bias systematic error is present). Outcomes from replications are fodder for refining, altering, or extending theory to generate new predictions.

For example, replicates can include variability from changing equipment settings between runs or variability from other environmental factors that may change over time. Recent attempts to systematically replicate published claims indicate surprisingly low success rates. Replication is not about the procedures per se, but using similar procedures reduces uncertainty in the universe of possible units, treatments, outcomes, and settings that could be important for the claim. 4 Why is scientific notation used quizlet? 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. Yes Replication 1 Repetition (noun) The act or an instance of repeating or being repeated. This is illustrated by a shrinking generalizability space in which the theory does not make clear predictions. When there is uncertainty about the status of claims and the quality of methods, there is no easy solution to distinguishing between motivated and principled reasoning about evidence.
