1)
please go to my website undergraduate resources link and then to the syllabus
at

**http://www.fordham.edu/economics/vinod/syllabus16spr.doc**

2)
download the pdf file of the free text from

your free internet textbook is at

**http://www.onlinestatbook.com/**

if
you have windows xp, 7 or similar computer

within
that folder create a folder called "onlinebook"

please
download the entire book multimedia version zip file and save it to that folder

unzip
the zip file and save unzipped version to your computer to the

the
unzipping software creates additional folders to this folder separate for each
chapter etc.

the
automatic folder names are, for example,
"\statistics\online_stat\chapter1\"

now
look at the pdf file for "descriptive statistics.pdf" file

and
also look at the movie with that title.
if you did the above steps right,

the
movies will be found in the folder with the path:

c:\stat1\onlinebook\statistics\online_stat\chapter1\movies

click
on the icon for "descriptive.mov" and listen to it

if
you do not have movie watching software, download it at

**http://www.apple.com/quicktime/download/**

look at version 2 and table of contents of the
online free book

**introduction** for a preview of the next class. try to do some exercises.(optional)
