Document Summary

Levels of measurement: nominal scale, for categories, no magnitude, no additivity, can code the data with numbers (ie. 1=male, 2=female, no mathematical meaning, frequencies within category are the only meaningful approach to quantifying, ordinal scale, also for categories, but those ascribed diff relative values, rank ordered, but not additive, no assumptions about equal increments. Temperature: units do not reflect true values , yet differences are meaningful within the measurement system, ratio scale (highest), highest level of measurement, essentially an interval scale with an absolute 0 (0 means total absence of whatever, can be subjected to most mathematical and stats analyses.
