Business Statistics with EXCEL

Some extraordinary data sources on the web:

The Data Ferret gives access to Census and CDC  data  gives links to a large variety of government sites with statistical data is an extraordinary resource for tools and data
The National Center for Health Statistics at CDC is a great central source on health statistics and microdata

Here is a web site I have found helpful.
Here is a database I found which has survey data.

Some Odd Issues with EXCEL


EXCEL may remove commas on import of comma-delimited data replace commas in source with another delimiter.
paste and parse in one step with the comma delimiter set in the import wizard
Tdist won't work with negative T scores and doesn't say why use the abs() function to provide the referenced number as a positive.


Simple Simulations of Statistical Concepts

ANOVA uses averaging to selectively eliminate variance due to different causes, allowing us to simultaneously measure the effects of different factors.
Anova is used when the dependent variable is continuous, but the factors are described as discrete categories
anovarat.xls has macros in it because it has a dropdown list used to set the level of averaging. set security to medium and allow EXCEL to enable the macros.
Multiple Regression. The Varsorc model visualizes the concept of multiple regression. We are able to  simultaneously detect effects of several variables. by mathematically correcting for all but the one of interest. varsorc.xls has macros in it because it has spin buttons. set security to medium and allow EXCEL to enable the macros.


HEY!! In Office 2007, where did the EXCEL menus go?

How to find EXCEL 2003 commands in EXCEL 2007 "Ribbons"
try downloading the Excel Ribbon mapping workbook.
I recommend clicking on the OFFICE icon at the top left of EXCEL 2007, click EXCEL OPTIONS (a button down at the bottom) and fix whatever needs fixing to get access to what you need, such as "Developer tab." Change the SaveAs default to old (1997-2003) EXCEL so you can still work on the product files on older versions of EXCEL. In case you have to, you might be able to find file converters at They are also promising to someday make their file formats open source. Uncommon fonts may also wreak havoc as you try to work on a file across machines. Change default font theme under "page layout." I know Times New Roman and Arial are uninspiring, but they are more likely to be on your other machine. After I get a feel for what needs to be fixed in the School's setup of EXCEL, I'll produce some guidance and videos on how to fix things, so you can relate my existing videotutorials to EXCEL 2007.
Microsoft has a compatibility pack for installation in older versions of OFFICE so you can read and write the new file formats. You need to install all the updates first.
if you can't use the link, then you can probably find it at the microsoft office site or google it.

Final Project- pivottables on the YRBSS2005 data in EXCEL 2007
You might also want to look at these if you are doing exercise 5 & 6 with EXCEL 2007. pivottables work a little differently in EXCEL2007, and the file formats don't convert backwards, so you can't easily work across versions. More on this as I study it further...

Table of Video Tutorials in Earlier Versions of EXCEL:

Some of these are EXE's  that include the viewer. In that case, you may have to save to the hard drive and run using window explorer or Start/ Run

These are FLASH format video files, small enough to download from home (if over the phone, eventually!).  You can borrow earphones to listen while playing them in School labs. Double click on the speaker down in the taskbar to remove muting and increase volume. plug the earphone into the green connector on the back of the computer. It uses a mini-stereo plug.
  For your convenience, these are widely available from students who have copied the course CD's.

    Data for the YRBSS 2001 & 2003 are on this disk, as well as NCHRBS 1995

    The videos below are with EXCEL XP and the YRBS 2001 and YRBS 2003 data as indicated. New data is released every two years at the CDC website. There is also a dataset there for the National College Health Risk Behavior (NCHRBS) conducted in 1995.
    There may be a new version of the NCHRBS in the near future, so it would be good to check the CDC websites from time to time. Data from adult risk behavior surveys and census data are available at the dataFerret site. For convenience, ASCII data and descriptions available now are linked here and are on this disk so you don't have to download it:
