What are you talking about they are this is a stupid question just like you
<u>A credible source of information is the reliable one, based on supporting evidence:</u>
A study by researchers published on a university’s website is a credible source of information as its validity is authenticated by the fact that the university has allowed its appearance on its formal website which is viewed by millions of users every day.
Another credible source can be a book written by a scholar on the topic with examples supporting his viewpoint. It will carry his point of view based on research which can be used by the researcher to make his study. Such books have been used by researchers in the past to improve the development of a topic and carry on their research.
