inherent problems related to LICKert items and level of measurement that
create problems would be these too
1. how many response categories are there for AN item??? by the way ...
likert used many types ... including YES ? NO
at THIS level ... i think it a bit presumptuous to think that we are
working with interval level measurement
2. what the labelling is FOR points ON an item ... i think it is easier to
pretend the item level measurement is interval IF the scale is in terms of
% agreement terms ... rather than SA ... SD kinds of response points
3. how MANY items there are ...
now, if you have FEW items ... with FEW points ... that are like SA ? SD
... then at the item or total score level ... i think it is hard to assume
interval level data ... if you have MANY items that each have NUMEROUS
scale points ... that are framed differently that SA to SD ... then
assuming interval level data is much more tenable ...
