True or False: Eye colors are an example of ordinal data.

This statement is false.  Eye color is not an example of
ordinal data.


Ordinal data are things that are ranked.  In
other words, when you look at things where there is a first, a second, a third and so
on, you have ordinal data.  But eye color is not this kind of data.  Blue eyes do not
come before brown eyes or vice versa.  Therefore, eye color is not an example of ordinal
data.


I would classify eye color as nominal data. This is
the sort of data where you have various classifications that are not ranked -- they are
just different.
