Hi there,
I am conducting a study using the National AddHealth data set.  After running factorial anovas, it is clear that I need to follow up with a trend analysis.  I figured out how to run graphs, but does anyone have information on running the statistical tests for trends.  The study has four continuous outcome variables, plus sex, age, and grade level with one  categorical independent variable.  Any help is much appreciated.
