APA (American Psychological Association) referencing is a way of citing research in your report. Citations are an acknowledgement that the idea or quote is taken from another source.
An example of an in text citation is:
It has been argued that “social media can be an excellent avenue for introverted people to find a comfortable setting to interact” (Jones, 2013).
Then, in the bibliography I would include the full information that links the reader to my source.

By far THE BEST resource to help you cite using APA is Massey University’s APA Interactive Guide USE IT!!!
If you are thinking of going to Uni this is an incredibly valuable skill to learn. Nobody told me how to reference at school and when I got to University I had no idea how to do it. So learn now and you’ll have a huge advantage.
