1.What type of level of measurement is a sleep diary (nominal, ordinal, interval, ratio)?
2. What type of LOM is a stress questionaire?
3. what type of LOM is a health questionaire?
4. what type of LOM is heart rate?
5. what type of LOM is exercise levels
nominal: Most basic, lowest level of measurement.Categories are discrete (“categorical”) and mutually exclusive. No math
ordinal:Numerical value that assigns an order to a set of observations – which allows ranking.Each category is mutually exclusive. Unequal spacing between categories. No math functions, but relative indications can be described.
interval: similar to ordinal, but has equal spacing. Indicates how much categories differ. Data are continuous in which zero is random. Unable to report ratios, but can report equal spacing.
ratio: highest level of measurement. Has prior characteristics, plus an absolute zero.
