Statistical variables can be measured using measurement instruments, algorithms, or even human discretion. Qualitative data is descriptive data like color, taste, texture, smell, etc. Ordinal variables can be placed in a logical, meaningful order while the order does not matter for nominal variables. These variables can be both nominal (they only serve to differentiate subjects into different categories) and ordinal (which, in addition to the above, allow an order to be established, although it does not allow mathematical relationships between their values to be observed). True False, Working Scholars® Bringing Tuition-Free College to the Community. Babbie, E.R. One has no more value than another, but someone with secondary studies must have done primary studies before, for example. They both refer to things that can be counted, even if it seems like it'd take a lifetime to measure.
