What non-metric variables do you think would usually exist in determining priorities for a business system of this magnitude?

#### Solution Preview

Please see response attached, as well as one article (includes both metric and non-metric variables) for your consideration. I hope this helps and take care.

RESPONSE:

1. What non-metric variables do you think would usually exist in determining priorities for a business system of this (and what magnitude is this?) magnitude?

There are two basic alternatives for defining a measurement scale for the dependent variable: metric (i.e., ratio scales, assuming approximately interval scale properties) or non-metric (i.e., paired comparisons, rank order).

Nominal and Ordinal Scale

Nominal is a scale where the numbers act only as data labels (e.g. 0=male, 1=female or a systems preference). The only analysis that can be performed is to observe how frequently each of the scale members occurs in the survey. Ordinal is a scale where numbers can be ordered according to importance or priority (i.e., service requests, customer satisfaction, demographic, and behavioral information of system users, etc. - see examples on each these non-metric variables below).
This question seems to addressing the Preference (importance) category (i.e., determining priorities). In most instances the respondents will be asked to estimate the priority of some measure of the system (i.e., order the importance of certain tasks) IN A SPECIFIC area of concern. It is difficult to name variables without knowing the ...

#### Solution Summary

This solution identifies and discusses non-metric variables that often exist in determining priorities for a business system of significant magnitude. Supplemented with a highly informative article about business decisions and analysis.
