Nominal. The Binomial and Poisson distributions are popular choices for discrete data while the Gaussian and Lognormal are popular choices for continuous data. Unlike the ratio scale (the fourth level of measurement), interval data has no true zero; in other words, a value of zero on an interval scale does not mean the variable is absent. Also, the value of 0 is arbitrary because negative values of temperature do exist which makes the Celsius/Fahrenheit temperature scale a classic example of an interval scale. Thats all folks!

Nominal Data is used to label variables without any order or quantitative value. So, although the ordinal level of measurement is more precise than the nominal scale, its still a qualitative measure and thus not as precise or informative as the interval and ratio scales. In a physics study, color is quantified by wavelength, so color would be considered a ratio variable. The categories still must be mutually exclusive and exhaustive, but also have a logical order that allows them to be ranked.
