Details on Formatting a PowerPoint in APA 7
"The APA manual does not have a section on how to format a PowerPoint presentation, but you can follow APA style guidelines within your PowerPoint. For example:
Include the same information on your title slide that you would have on a title page.
Include in-text citations for any quote, paraphrase, image, graph, table, data, audio or video file that you use within your presentation. Please note that photographs are considered figures in APA style. See section 7.30 of the APA manual for more information about this.
The last slide will be your References List.
“No citation, permission, or copyright attribution is necessary for clip art from programs like Microsoft Word or PowerPoint” (American Psychological Association [APA], 2020, p. 346).
Do not reproduce images without permission from the creator or owner of the image. See section 12.15 of the APA manual for more information about this."
