External validity refers to the extent to which results from a study can be applied (generalized) to other situations, groups or events.
The validity of a study is largely determined by the research design: what, how, where and when the study was executed.

This quick guide, based on The Chicago Manual of Style (17th edition) explains how to create Chicago style citations. Other well-known citation styles are MLA Citation Style and APA Citation Style.
Chicago Style has two systems for citing sources:
- Notes and Bibliography, which works with footnotes or endnotes, often accompanied with a bibliography. This system is mainly used in humanities subjects.
- Author-Date References, which works with in-text citations (reporting only the author and publication date). In-text citations are always accompanied by a bibliography. This system is mostly used in sciences and social sciences.

APA in-text citations consist of the author’s last name, publication year and, if applicable, page numbers. Page numbers are required when quoting and encouraged when paraphrasing. Omit page numbers when referring to a source as a whole.
In-text citation can be included in multiple ways:
- The author claims that “plagiarism is becoming a bigger problem” (Smith, 2014, p. 170).
- Smith states that plagiarism is an increasingly big problem (2014, p. 170).
- The study of Smith shows that plagiarism is an increasingly big issue (2014).
The free Scribbr APA Citation Generator can be used to easily generate your apa in-text citations (and full reference list entry).
