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.
It is on all the computers in Macmillan 101, and on the Dells in the
Social Sciences Lab (Mac 304).
NOW also in Main! And
Weld!! (9/7)
Files for Homework: They should be in the Class
Material folder, Math 151BPS4e. On newer computers, this is on a
drive labeled DATA. On older ones, it may be on a drive
labeled STUDENT.
The Letter identifying the drive/device may vary. You can find it
by opening the Class Material folder on the Desktop, and looking in the
Address line at the top. There will be a letter like F:
or D:. Use the pull-down arrow in the Address line to see
what the name of the drive is. Knowing the name and/or the letter
of the drive will allow you to find it from within SPSS. The
folder PC-SPSS has the textbook problems. PCBPSbigdata
has some text files for bigger datasets. The files must be opened
from within SPSS. They are not in standard SPSSv.14 data type, so
you have to change Files of Type to All files to see
them in the Open File menu.
PC-SPSS and PCBPSbigdata are also on the CD in your
book, but 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. Find and click on the drive
with the BPS4e CD in it. Open the PCDatasets
folder. PC-SPSS and PCBPSbigdata are folders in
there, the same ones as in the Class Material folder.
(If you want to find these files outside SPSS, say to copy them
to your laptop, do this: 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 BPS4e
CD in it. Open the PCDatasets folder. PC-SPSS
and PCBPSbigdata are folders in there, the same ones as in the
Class Material folder.
Ugh! Output files created and saved on some computers, especially
those with SPSS newly installed, cannot be opened by some (other?)
computers!
I'm trying to figure out just how and when this goes bad... Any info
you have will help me! sievers@wells.edu. Meanwhile, if you can't
print it out right then, cut and paste into Word. Update:
Computers in Mac 101 can save and open their own or other Mac101
output files OK. They have beige frames on the SPSSwindows.
But can't open output files from Weld. Main?? Does Weld
have gray frames?? We think the
gray-framed is a slightly newer version, and it's not compatible
"backward."
Cut and paste problems? Reports of pasted things into Word
being too
big or not printing. I haven't been able to reproduce this
effect. Please give me more details, come show me.
Flash drive trapped? I've seen
today two instances of closing SPSS, doing the Safely Remove Hardware
button, and it saying the flashdrive was still in use. SPSS
should be, but isn't really closed. Do this. Hit
Ctrl-Alt-Delete, all at once. You'll get the Windows Task
Manager. Click the Processes tab. If spsswin.exe is at the top of
the list, make sure it's highlighted, and click the End Process
button. That should free you. Only
happens on beige-framed version after it's refused to open an output
file made on a gray-framed version.
