1. American Psychological Association (APA) uses four basic principles, that is, author (who is responsible for the work?), date (when has the work been published?), title (what should the work be called?), and source (where could the readers retrieve the work?)
2. In the reference list, please do not put a period after a DOI or URL because it may interfere with link functionality.
DOI: (correct) (wrong)
URL: (correct) (wrong)
3. Reference should be written on a separate page, with the format cantered, bold, and capitalized (title-case)
4. There are rules regarding how the names of the author/s in a reference should be arranged
5. There are various types of reference according to APA 7th edition, which are broadly based on four sources: (1) textual workgroups [e.g., journal articles, books, theses/dissertations, etc.], (2) data sets, software, tests group [e.g., raw data, test scoring, etc.], (3) audio-visual media group [e.g., YouTube video, PowerPoint slides, etc.), (4) the online media group [e.g., Instagram photo, tweet, etc.].
