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 licensed to Wells only for college computers. You probably don't need it, but if you want your own copy, see SPSS for your computer.(may need updating)
Where? SPSS in Mac 101,
Main computing lab, PC's in the Long Library
Learning Commons. Please let your prof.
know if SPSS is not working on any of these machines (with lab and
Printing: Windows 7: In SPSS, choose Microsoft XPS Document Writer as your "printer", your output will become an "xps" file. Save it and print thru Papercut.
Remember, your option is to copy (one at a time) the graphs from SPSS and paste into a Word document. Then save the Word document and print that thru Papercut (which will print Word docs directly).
Data Files for Homework: Math
151-Moore5e folder (Feel free to copy
the folder(or any part) to your own USB drive/ computer.)
Where is it??
On Windows 7, (Mac 101 and Main, Learning Commons
), it should be in
C:Users>Student>Documents>Class Material >Math 151-Moore5e.
(In Main, the Student folder may also show on the Desktop, Class Material inside that....)
You can enter Class in the Search box and it'll get you there, unless the folder's been deleted.
From within SPSS,
File>Open>Data may open in the Documents folder (Windows 7) where you can find Class Material etc.
Macintosh (Mac 110), or can't find files on
Windows machine: Data Files
The Math 151-Moore5e 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 in SPSS
portable, not in standard
SPSSv.22 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 (if you have one) 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 USB drive, 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. For other operating systems, find the CD drive from My Computer or equivalent, go from there.)
Ugh! Every time we change versions or computers we find new problems! If you have trouble, please email your prof with as much detail as possible.
--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. Don't depend on
stuff you leave on a computer staying there; get a flash drive.
