Research variables
named; measurement
and possible values of
each variable clearly
defined.
Each research variable is
represented with
appropriate, clearly
labeled, charts and
tables to support the
narrative explanation
(see Descriptive
Statistics)
Each research variable is
fully and appropriately
described.
