SPSS is a powerful computer package that does
statistical analyses of data. It has been developed over many
years and is like a huge house that was built in stages, in many
different architectural styles. So there may be several ways to
do almost the same thing, but it may come out slightly different in
each way. KEEP NOTES when you figure out how to do
something you might want to do again.
SPSS is licenced to Wells only for college computers. You probably don't need it, but if you want your own copy, see SPSS for your computer.
Where? IS in Mac 101,
PC's in the Learning Commons, Cleveland, Mac 110 (Macintoshes)
Files for Homework: Math 151-Moore5e folder (Feel free to copy the folder(or any part) to your own USB drive/ computer.)
In some computers around campus, especially those running
XP, they are still on the desktop, in the Class
Material folder, which contains
Elsewhere, you'll need to connect to \\Morganstore: See Handout
The folder PC-SPSS has the textbook problems.
PC-BPSbigdata has some text files for bigger datasets. The
files must be opened from within SPSS. They are not in standard
SPSSv.19 data type, so you have to change Files of Type to
All files to see them in the Open File menu.
The CD in your book also contains PC-SPSS and PC-BPSbigdata, but it's not so obvious.
Insert the CD, wait till it opens. Ignore it.
From within SPSS, File>Open> Data. Pull down the arrow on the Look in box at the top. Find and click on the drive with the BPS5e CD in it. Open the Datasets folder. SPSS and PC-LargeData are folders in there, the same ones as PC-SPSS and PC-BPSbigdata in the Class Material folder.
(If you want to find these files outside SPSS, say to copy them to your laptop, do this for XP's: Right click on the Windows Start button (bottom left of your screen). Choose Explore (second from top, usually) from the menu you get. In the left pane of the resulting directory window, find and click on the drive with the BPS5e CD in it. Open the Datasets folder. SPSS and PC-LargeData are folders in there, the same ones as in the Class Material folder.
Ugh! Every time we change versions or computers we find new problems! If you have trouble, please email me with as much info as possible: firstname.lastname@example.org
--Save your work frequently! (see above.) The Output file saves
separately from the Data file (save that too if you modified it in any
way.) The Output files tend to be quite large. Delete stuff that is
wrong or useless, to save space and confusion. And the Lab
computers all REBOOT automatically between midnight and 1 a.m. and
you'll lose everything not saved!
