The 4 levels of measurement
Data at the _____________ level of measurement are qualitative only and are categorized using names, labels, or qualities having no effect on mathematical computation.
Data at the ___________ level of measurement are qualitative or quantitative, and can be arranged in order, or ranked, but differences between data entries are not meaningful.
Data at the ____________ interval level can be ordered, and meaningful differences between data entries can be calculated. A zero entry simply represents a position on a scale; the entry is not an inherent zero ( a zero that implies "none").
Data at the _____________ level of measurement are similar to data at the inherent level, with the added property that a zero entry is an inherent zero (a zero that implies "none").
