As I remember it...

If 4 concentric circles represent a Venn diagram for the four levels of data then "nominal" is the outermost, containing "ordinal" which contains interval which contains ratio. E.g any "interval data" is by definition also "ordinal" and "nominal". Any statistical test involving 2 different levels will be aimed at the lowest level of the two.

e.g. In testing a relationship beteween salary and IQ we can assume salary is interval but IQ is only ordinal. Therefore we simply order the salaries.....even if" A earns twice as much as B" we can only use "A earns more than B " because we cannot say "A is twice as intelligent as B".

Your different types of education will be ordinal if one type depends on achieving another. e.g. "College" depends on "high school". However if we have "vocational training" versus "academic study" we can only assume nominal. In a mixed set use the lowest level.

I hope this makes sense.

Well I think if A earns twice as much as B then A is twice, if not more, as intelligent as B.

The rest is bullshit.

Andy Warhol taught me that and I love him for it.

crayon,

Note, if an experimental subject is forced to rank "vocational" versus "academic" then you are back to ordinal.

I am actually humbled by how much more intelligent Richard Branson is than I am.

I have learned to live with it.

Intelligence isn't everything.
Trust me, I know.
