User:Dpleibovitz/sandbox/List of numbered classification classes

< User:Dpleibovitz | sandbox

This is a list of alphanumerically numbered classification classes (using well known collection concepts), e.g., "Group 1", "Group 2", "Class A", "Class B". For an entry to appear in this list, it must be part of a classification scheme, i.e., it must produce at least two numbered class categories. These become informal Category:Equivalence classes.

Alphanumeric numbering can imply an ordering (or rank), possibly arranged hierarchically, or it can be an arbitrary nominal number. These are also indicated. When letters are used in roman numbering schemes, they are sorted numerically, otherwise, alphabetically.

Level of Measurement (LoM)

edit
Main article: Level of measurement

Note that this is a graded/Ordinal scale of increasing mathematical uses. Would like to call this "measurement class" as WP:OR, and include similarities and graded scales, e.g., beginner, intermediate, juniour

Similar

edit

Name? Technically, many non-physical scales are similars, in that there is no perfect external construct validity. A grade of B in a great university may be worth more than an A on an online university. Indeed, such gradings can differ in meaning (measure of student understanding) between professors, departments, universities, states/provinces, countries, and it is not clear what a failing grade for a bored and unchallenged genious actually means. Percentages fall in here (and thereby the discretized grade). No talk about the kind of error. This proscriptive typology is more about meaningless numbers.

Nominal

edit
Further information: nominal data

Nominal data has no meaningful order. One can test for equality of inequality, but not for greater than. No distance - no metric. The #Notes can still indicate the bases of equivalence.

Ordinal

edit
Further information: Ordinal data

Note that graded types (like the Level of Measurement) are named, have an order, but are not numbered. Note that many "scales" cannot scale as this requires multiplication by a scale factor that is only supported by ratio data. These could be called indices.

Grade
edit

Error: no page names specified (help). A grade is simply a named (enumerated) ordinal, e.g., beginner, intermediate, senior

Draft questions to be resolved

edit
  • Title?
  • Don't want to include Category:ISO standards because "ISO" is not a general grouping/collection/
  • What is the best word for a collection: grouping, classes, collection?
  • class 1 is a prototype for equivalence classes
  • Ordered change to scale. My need citations for synthesis.
