Reproducibility, closely related to replicability and repeatability, is a major principle underpinning the scientific method.For the findings of a study to be reproducible means that results obtained by an experiment or an observational study or in a statistical analysis of a data set should be achieved again with a high degree of reliability when the study is replicated.
A low p-value in a replication study indicates that the results are not likely due to random chance. [6] For example, if a study found a statistically significant effect of a test condition on an outcome, and the replication find statistically significant effects as well, this suggests that the original finding is likely reproducible.
Proliferation, as one of the hallmarks and most fundamental biological processes in tumors, [1] is associated with tumor progression, response to therapy, and cancer patient survival. [2] Consequently, the evaluation of a tumor proliferative index (or growth fraction) has clinical significance in characterizing many solid tumors and hematologic ...
The major advantage of T-RFLP is the use of an automated sequencer which gives highly reproducible results for repeated samples. Although the genetic profiles are not completely reproducible and several minor peaks which appear are irreproducible the overall shape of the electropherogram and the ratios of the major peaks are considered ...
Predominance diagrams can become very complicated when many polymeric species can be formed as, for example, with vanadate, [4] molybdate [1] and tungstate. [1] Another complication is that many of the higher polymers are formed extremely slowly, such that equilibrium may not be attained even in months, leading to possible errors in the ...
An ICE table or RICE box or RICE chart is a tabular system of keeping track of changing concentrations in an equilibrium reaction. ICE stands for initial, change, equilibrium . It is used in chemistry to keep track of the changes in amount of substance of the reactants and also organize a set of conditions that one wants to solve with. [ 1 ]
Genomic markers as mentioned, have particular strengths and weakness, so, consideration and knowledge of the markers is necessary before use. For instance, a RAPD marker is dominant (identifying only one band of distinction) and it may be sensitive to reproducible results. This is typically due to the conditions in which it was produced.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
