Since a Wikipedia article can be written and changed by anyone, and it does not have an author listed, do you need to cite it as a source?

Yes, you should still cite Wikipedia as a source if you use information from it in your work. Even though Wikipedia articles can be written and edited by anyone and do not list an author, it's important to give credit to all sources of information you use. This helps maintain academic integrity and allows others to verify the information if needed.

Here's a step-by-step guide on how to cite a Wikipedia article in APA style:

1. Start with the title of the article in quotation marks. This is the equivalent of the author for the citation.

2. Next, write the year that the article was published. If this is not available, use the date you accessed the article. This should be in parentheses.

3. Write the title of the source. In this case, it would be Wikipedia.

4. Finally, write the URL of the article.

Here's an example:

"Title of Article." (Year). In Wikipedia. Retrieved from URL

Remember, while Wikipedia can be a good starting point for research, it's not considered a reliable source for academic writing. It's best to use peer-reviewed articles and books for your research.
