Subject: Tracking students - longitudinal study
Content-Type: text/plain; charset=ISO-8859-1
I'm collecting data on students from 3 different points in time.
Given I have a unique id for each student, and for each point in time
I have a different database, how do I go about in tracking the
student? That is, what is the best way to know if student X
participated in time 1 and time 2? Or if student X just participated
in time 1?
I am thinking that an IF THEN statement should work, but am unsure
exactly how to write it.
