REPLICATIONS OF RESEARCH AND IT'S SCIENTIFIC BACKGROUND

Replication is the principle of Research. Replication means a repetition of the basic research. This article focused on replications of experimental research and its scientific background. In all experimental research study, some variation exists because the research units, such as samples, time, geographic condition, weather condition, psychological factors, primary and secondary information, extraneous variables interactive and reactive factors, which cannot be physically identical, therefore its influence cannot be controlled during the experiment.

Replication in physical education is also important, to collect evidence for the application of a particular program (X). However, the principle of replication is ignored by the physical educators. Focus on new problems, Non-Professional Researchers, Research for only Degree etc., may be the reasons for non-replication in physical education.

The replication studies conducted compare the original results of the basic experiment as well as attempts to validate the findings of a prior piece of research. Replications help to determine the influence of across Time, Area, Condition, Sampling and Method factor. More trials of replication provide more results and its average will be close to the expected value. More time tested any program is always better and eligible to generalize. Hence, based on ‘Law of Inertia of Large Number’, replications of the basic experiment are always helpful to increase validity of the result of basic experiment.
