Have you ever thought about a scientific research, scientific method, peer review, statistical significance, and the like? Have you ever struggle for new things? Scientists like to find new things and compose something about them: That is what we mean by scientific research! In fact, “Scientific research is the systematic investigation of scientific theories and hypotheses.” 

And what about research itself; Research contains "creative work undertaken on a systematic basis in order to increase the stock of knowledge, including knowledge of humans, culture and society, and the use of this stock of knowledge to devise new applications. It is used to establish or confirm facts, reaffirm the results of previous work, solve new or existing problems, support theorems, or develop new theories.”

Usually researchers want to understand how the world is run and inform others about the issue. They usually do this through making hypotheses about the available data. They are usually Ph.D. holders in a particular area and conduct their experiments on behalf of an institute or university. Their investigations can sometimes be something out of mind. For example life symbols on other 
Planets or dangerous effects of a special rare dug. However, these rare cases are very important since they can affect us in some way. 

To answer their questions, scientists need to use scientific methods in order to reach more accurate conclusions about their hypotheses. This method can help the human being draw a finer picture of the world and the way it works. Understandably, they do so through these steps: 
•    Observing the world
•    Making hypotheses about them
•    Testing the hypotheses with experiments
•    Analyzing the results to see if their hypotheses were true or not 
But what about a scientific research…. What makes it different from a dogma? Yes, no prejudice; in other words, personal belief and prejudice have no place in what a researcher does.  That’s why you can repeat it as many times and reach somehow similar results. The other crucial point in a scientific research deals with the falsifiability of a hypothesis. In fact, hypotheses need to have the potential to be wrong, untrue, or false through conducting different experiments.

“Overall, scientific research helps people come up with rational, objective, testable, and disprovable questions and methods that help us explain the world and its ever-changing nature.” Through science, bias is meaningless, you can test anything and accept or reject it. That’s why we say it is an objective and unbiased method. 
However, unbiasedness and objectivity cannot guarantee a scientific experiment. Some other factors need to be added to make it more valid and reliable. However, these refer to the period after conducting the experiment. Peer review process is the first step. It is the process in which the scientific experts who are not involved with the study see if the work meets scientific accuracy, proper methodology, and relevancy. In fact, scientific peers check whether the paper comes up with the expected qualities of a scientific paper or not. In this case, the possible issues and mistakes can be solved.
