1.Explain what makes a scientific experiment reliable. Be sure to include at least three reasons to support your answer. 2.During research, why is it important to use peer reviewed evidence when collecting background information during a scientific investigation?

An experiment is reliable when its repetition produce always the same result. In science, peer review is fundamental because this process ensures that there is not misleading data that may lead to erroneous results.

In sciences, reliability is a term used to evaluate the quality of research. Reliability refers to the probability that an experiment or result is correct, thereby preventing and mitigating failures over time.  An experiment whose successive repetitions conduct the same result is 100% reliable.  Three examples of reliability in science: the same measurement of the size of the leg of a spider. the observation of the same behavior of birds populations on different days and at different times of the day. the same byproducts from a given chemical reaction when an experiment is repeated two or more times. Peer review is the most widely accepted process used to validate scientific data. This process (peer review) is fundamental to facilitate the growth of scientific knowledge. During peer review, independent scientists assess the originality, reliability, and significance of a scientific work before its publication.
