Hi all...
Wondering how to perform a tertiary split, either in spss or excel.
I have taken a measure of anxiety from participants, and would like to
create 3 groups..low, medium, and high anxious, but not sure how to create
the group boundaries in terms of their anxiety scores. Essentially, I want
to look at only the high and low people, and disregard anyone in the medium
group to look for maximal effects. (When I initially wanted high and low
groups i simply found the median, and scores above where assigned to high
etc). Can i perform a tertiary split (if that's what it's called!) in spss
or excel?
Thank you in advance for your help!
