Which resource would be considered most credible? a.) an article published in a scientific journal b.) an article on wikipedia describing the scientific method c.) a blog about the writer's own experiment d.) an essay about science in a popular magazine

I believe the correct answer is: A.) An article published in a scientific journal.

     Credible sources (or reliable) are scientific material that are approved by the scholarly community, and are therefore regarded as reliable. Materials such as articles, books, monographs, or research papers that have been published in reputable peer-reviewed sources, or by well-regarded academic presses, are credible sources that one can use in their research to back up his/hers arguments. These materials can usually be found in libraries, and sometimes on the Internet. Therefore, the credible source can be found in a scientific journal, as it is approved by the scholarly community.

     An article on Wikipedia describing the scientific method cannot be regarded as credible source as anyone can change the statements/facts.

     A blog about the writer's own experiment cannot be credible as it is a subjective and unapproved by other scientists.

     An essay about science in a popular magazine cannot be a credible source as it is published in popular magazine and, therefore, not approved by scholarly community (as it is in scientific journal).

the writer needs to avoid using abbreviations and check spelling before sharing.
