Don’t forget that referencing is an important part not only of your grade but for your academic integrity as well. It is important to acknowledge other author's ideas that have influenced your work or that you have adapted to your work and to avoid plagiarism.
To do this in APA style you have to note two things:
APA (American Psychological Association) is one of many referencing styles used in academic writing. The Association outlines the style in the Publication manual of the American Psychological Association (7th edition) on which this guide is based.
The APA style is usually used in the social sciences but in many other scientific fields as well.
In academic writing it is important that you cite every idea, information or data that you have borrowed or derived from another text. In this way you give recognition to the original author and avoid plagiarism.
Note:There are several ways which you can use to integrate the ideas of others within your text.
