APA style regulates formatting for papers in the social sciences. It covers stylistic elements like using the third person rather than first, active voice instead of passive, and clear, concise, plain language. APA also governs in-text citations, references lists, and various paper sections and their formatting. Common APA paper types include literature reviews and experimental reports. Papers should follow a general format including title page, abstract, references, and main body sections. In-text citations and reference lists are formatted according to specific APA rules.
