Statistical Problem Descriptives

a. If ratio-level data is more restrictive (e.g., order, distance, and origin), should your research focus on nominal variables? Why?

b. If we assume ordinal-level scales are interval, does this create errors?

c. If I assessed a respondent's attitude, for example, to food taste would I have identical measures on six consecutive days?

d. If I measure a psychological variable longitudinally and receive identical measures, is it reliable?

e. If zero indicates the absence of something, do you have a ratio or interval scale (assuming order and distance)?
