I modified the source so you can link to a measurement type using a HTML label.

Just put in Nominal Measurement

Definition of Levels[edit]

This article should clarify the meaning of the word level at the very beginning, and disambiguate it from a related meaning. The word level is used two different ways in this article. Besides its primary meaning (a type of measurement), here is a sentence fragment from this article where it is used differently:

...any difference between the levels of an attribute can be multiplied by...

The same use of level occurs in the Wikipedia article on Theory of Conjoint Measurement in this sentence fragment:

...Via specific relations between the levels of P...

In these cases, it appears that the word level means a particular value of a nominal (or categorical) variable (or measurement). The programming language R has a type of variable called a factor which is used to represent categorical variables, and its individual values are called levels, which seems to again be the same meaning of that word as the above two. This use of the word level seems to be quite common and used freely as if any educated reader will understand it, but that understanding of level is not that widespread.

Likert scale as example of interval level?[edit]

I was surprised to see the Likert scale given unreservedly as an example of interval-level data. Surely this assertion is a bit controversial and should at least have a caveat.

Also, it should have a hyperlink to the Wikipedia entry for Likert scale, (where, incidentally, the issue of whether it is interval or ordinal is teased out a bit more).

Likert scale[edit]

I could not find anything mentioned on the page regarding Likert scales. Given how often these are used, as well as some important influences about how you label the possible discrete & ordered choices, I think that they should at least put in a brief cameo appearance.

Please indicate whether or not you agree with the assertion that Likert scales should be included as part of this entry:

  • Strongly agree
  • Agree somewhat
  • Neutral, neither agree nor disagree
  • Disagree somewhat
  • Strongly disagree

Citation style is a mixture of inline and the standard refs[edit]

Anon 2602:304:cfb2:7240:41bf:e3b2:4c7c:a42c has kindly pointed out that the citation style is a mixture of inline (e.g. Ferguson et.al., 1940) and the standard refs. --Ancheta Wis   (talk | contribs) 17:24, 17 September 2014 (UTC)

I really like the citation style suggested in User:RexxS/Cite_multiple_pages and would be happy to move this article over to that style, as I have several of the references at hand in my office. -- WeijiBaikeBianji (talk, how I edit) 18:31, 17 September 2014 (UTC)
