APA 7th edition is the newest version of APA, released in October 2019. APA provides a structured way to format your papers, include in-text citations and references, and avoid plagiarism. Here is more from a UCF Libraries Research Guide on APA 7th edition. In addition, the "How to..." Videos tab at the bottom of this Research Guide has several helpful short videos on citation.
Be certain of which version of APA your professors requires. If your professor requires the 6th edition, the Purdue OWL (link in the box below) provides information on this older edition until 2021. Here are some examples:
