processing eprime data

[David Hairston]

As a general rule, I do not use E-Data Aid at all; I use SPSS for 90% of
my analyses, and Excel for transitioning the data between E-Data Aid and
SPSS. Personally since I know that I'll need everything in SPSS for
eventual stats, groups for figures, etc etc, I find it easier to go
there directly.
So, when the experiment is done, I immediately group it via E-Merge,
then export into Excel Test format... then I open it via Excel, and go
through and trim out all the stuff I don't want (Mike I know what you
mean about a LOT of irrelevant stuff). The nice thing about doing this
in Excel is that you can easily record a macro to delete all the things
you don't want, so you can do it again later w/ a few clicks. This also
gives me a chance to change variable names to be SPSS-friendly, etc.
Then I just port it back out into tab-delineated text, and import into
SPSS from there.

I, too, am curious to see what other folks do... 

Unfortunately as a result I do not know how to handle the block/ NULL
data in E-data-Aid, sorry.

Dear List,

I'm wondering how much preprocessing people are doing in edata aid
before going
to a stat package.  I've seen that most postings reflect programming
issues and
I'm wondering how people are processing their data, post-collection from
edata
aid. I'm hoping that his post will open this for discussion.

Because data is stored trial variable by block, there are many null data
values.
 Is there any ideal way for handling this in edata aid?

Also, some of the data we've opted to store, in retrospect, are
irrelevant.  Is
their a way to batch process files in edata aid to drop irrelevant
variables?

Thank you for all your responses.  If there is a good response to this
post, I
will compile the feedback for the list.

best wishes,

Mike Crowley
