Q. How do I cite the library website in APA format?
I obtained information from the website about statistics.
It depends on what information you are using from the website. If you are using one of the items from the newsfeed, then you could use this format, just substitute our website in the the retrieved from part. Here is a cite to help with citing https://owl.english.purdue.edu/owl/resource/560/10/

If you got to the information on statistics by going through the library's website, perhaps by using CentralSearch or the database A to Z list to find a specific article or online resource then you would cite the actual source of the information - e.g., the article or ebook that you found - rather than the library's website.
