Excel
Please work thru at least the first 18/19 lessons of the Excel 2013 / Excel 2016 introductory tutorial (not specific to statistics). The rest of the tutorials are useful, but I would consider more advanced than what we need for the class. [For those who will be using mainly MS Office 2007 or 2010, there are similar tutorials on the same site.] At the beginning of session 2, you will be have to do some writing on this material. Here is a self-quiz to see if you are ready.
excelnotes and excel2010_stats are guides more specific to statistics.
