Alternatively, if interactions are significant, then I recommend breaking up your analyses if possible. Analyze one group of data from a chosen categorical variable separately from the other group(s) of data.
Case 1 - Data
In this example, you have a continuous x-variable (e.g.,
mast crop - the estimated amount of tree seeds produced in a given year [kg/ha])
and one categorical x-variable (pine forest vs mixed hardwood forest) and you are looking at their effect on squirrel density (squirrels /
hectare). In this system, there is an interaction between mast crop and type
of forest. Write example sentences that you might include
in a manuscript for publication that describes the observed results.
Case 2 - Data
In this example you have a categorical x-variable (QDM
(Yes) vs.
non-QDM (No), where 'QDM' stands for 'Quality Deer Management' which is prescription
for managing deer in a way that supposedly improves deer quality) and another
categorical x-variable (sex), and you are interested in the relationship
between those variables and adult body mass (kg) in deer. Write example sentences that you might include
in a manuscript for publication that describes the observed results.
