APA is an acronym for the American Psychological Association. The APA format is a style of documentation of sources used by the American Psychological Association. It is mainly used by researchers and students in the social sciences, for example, anthropology, psychology, sociology, etc., as well as those in education and other fields. (The key differences between MLA and APA)
The APA format was first published in a psychological bulletin in 1929, the article laid out the basic guideline of the referring format. Subsequently, these guidelines were developed into the APA publication manual. The APA was initially proposed for the social sciences in an attempt to allow researchers and students to communicate information about their experiments and ideas in a consistent manner.
Having a consistent style and sticking to it will allow readers to know how to look for and locate the sources cited in journal articles in a particular field. The APA citation guide provides the necessary information on how to go about the in-text citations as well as the reference page. (Can you cite Wikipedia?)
APA, over the years, has become one of the most common referencing formats among others like Chicago and MLA referencing formats. When writing a paper, it is essential to know which referring format you are to adhere to. However, if you have never used a particular format before, you might find it rather challenging, as different formats have different writing styles and guidelines.
How Does the APA Format Work?
When you are using the APA format, there are two main things you need to know. They are In-text citations and the reference page.
You are expected to include an in-text citation when you are summarizing, paraphrasing, or quoting another source. This is a clear and concise way to let the readers know where the idea came from as well as a great way to give credit to the original author. For every in-text citation, there must be a corresponding entry included in your reference list.
In APA’s in-text citation, you are to use the author’s last name and the year of publication, all enclosed in parentheses, for example (Smith 2020). When you are quoting a source, it is important to include the page number where the quote is located, for example (Smith 2020, p. 6).
In the in-text citation of the APA style, there are no distinctions made between journal articles, books, website documents, or any other source type. Unless for the quotation of electronic documents that do not provide a page number. In this case, you are expected to use the paragraph number.
When Citing in APA Format:

Reference List – APA Format
At the end of your paper, you are expected to include a list of references, that is a single list of all the sources you have used and cited during your work. The reference list should be on a new page and be titled “References.” The title should be centered on the page; more importantly, each entry should have a hanging indent.
Every source that has been cited in your paper must be included in your reference list. Each reference entry must consist of the author’s last names followed by the initials followed by the date or year of publication, and the title of the source. Also, you are expected to list each item alphabetically by author’s last name, the title of the source should, however, be in italics.
However, unlike the case of in-text citation, the referencing format differs from source type to source type. Therefore, the necessary information that should be included is dependent on the type of source you are referencing. Variations include:
