Detailed explanation-1: -A scientific experiment is replicable if it can be repeated with the same analytical results. Due to all sorts of factors, including random variability, this is not as common as some might think.
Detailed explanation-2: -Replication of a study is repeating a study’s procedure and observing if the prior findings repeat in similar conditions. A study is replicated when the results of original study are as closely related to the newly collected data.
Detailed explanation-3: -If research results can be replicated, it means they are more likely to be correct. Replication is important in science so scientists can “check their work.” The result of an investigation is not likely to be well accepted unless the investigation is repeated many times and the same result is always obtained.
Detailed explanation-4: -Results may change over different trials or different conditions. Therefore, it is important that the experiment itself should be repeatable. A repeatable experiment should yield the same results when conducted by different people at different times and preferably-but not necessarily-under similar conditions.
