A peer review is the practice in which the research document is submitted to the experts or people who have the knowledge of the subject in which the research has been conducted.

The experts check the validity of the research and they evaluate the research work with their all set parameters. These experts find mistakes in the research document and present them to the researchers so that these mistakes can be corrected. This procedure increases the accuracy of the research document.
