I was writing a research paper that required me to use quotes and cite the websites/databases those quotes came from. Later, I needed some quick stats, so I googled them. I only used the numbers and didn't quote the website; I put it into completely different words. Do I still need to cite it? If so, then what should I put in my annotated bibliography for that source?
It sounds to me like you don't want to cite this source because you don't know how to format it in your bibliography. This is a terrible reason for not citing a source. If you can't figure out the appropriate format, make one up. I can assure you that the source would much rather be cited with an improper format than not be cited at all.
There may be good reasons for not citing a source (for example, if you're being helped by somebody whose company doesn't think he should be spending time on this kind of work), but I don't think you have any of them.
