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.
Where? as of Day 1
(email me , the class, with info: I'll update
this
list)
Mac 101. Mac 110. Mac 304. Not on any Macintoshes!
I believe it is also in Stratton, Main, Weld. Other
locations? Let me know!
Files for Homework: (Feel
free to copy the Class Material/Math 151-BPS4e folder and take it
to non-Macmillan computers (put it in theStudent folder, if there's
no Class Material folder on the desktop. Email us where.)
On Macmillan computers, they should be in the Class Material folder,
Math 151-BPS4e. 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.15 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 PCBPSbigdata,
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. 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! Every time we change versions or computers we find new
problems! (V.16 is new this spring.) If you have
trouble, please email me with as much info as possible:
