From the first class we're going to zoom along!  So you should get a head start before the semester begins.  Two main things:

·         Review basic stats

·         Figure out the basics of how to use R

 

Basic Stats

This class is meant for students who have a decent background in basic statistics.  In my experience teaching it, many students don't know if they have a decent background in basic stats – that's the whole problem.

 

So I'm going to be giving a diagnostic test about 2 weeks into the semester that you can take online.  It will only count for 10% of your grade but if you do poorly then I would encourage you to drop the class.

 

You can prepare for the test in a very simple way: use the online Hawkes Learning System, which gives straightforward explanations of each topic and then allows you to do lots and lots of practice problems, which is the best way to ensure that you learn those topics.  The Hawkes System isn't free (it's $55) but it seems a reasonable expenditure: if it saves you at least 5 hours of work then, given recent proposals for a $10/hr minimum wage, it's worthwhile (your own shadow wage might be higher).  Since the review material is available online you can start going through it from wherever you are, to get a jump before the semester begins.

 

I have set up the Hawkes System with recommended practice sections, although you can explore the other topics – there are lots of stats concepts that are good to know in general even if they're not absolutely necessary for this semester.

 

Then there's a test on the Hawkes System that you can take, so if you want to get it out of the way early you can do so, or you can wait until term begins.  If you don't want to use the Hawkes system (and there is a 'try before you buy' option so that you can make a well-informed decision) you will take a variant of the test once the term begins.  Either way you have to take the test by midnight (local time) on Sunday September 14, 2014.

 

To download the software, go to http://www.hawkeslearning.com/ all of the directions are there.  You will be asked for a "Hawkes Course ID," use CCNYSTAT.

Using R

The other way to get started on class work is to download and install the statistical analysis program R from http://www.r-project.org/.

 

If you haven't got a computer of your own, the Hawkes software is available in the CCNY computer lab in NAC 6-150.  The R program is also available there.
