Document Summary

These are all used for countable things. Another way to think of numbers is a point in a linear continuum or a number line. Rational numbers: this means ratio, this can be written as a ratio to two integers. Irrational numbers: do not end or repeat a sequence of digits. Measurement is a process of using indicators to represent constructs. A construct is a conceptual continuum that serves to organize our experience of the world. An indicator is a feature of the world. A score is the outcome of a measurement process it"s a number that"s assigned to the indicator to serve as a measure of the construct. Score = the number on the celsius scale. Every measurement instrument is designed to serve a particular purpose. The meaning of a score depends on its place among other scores. Words are a complex system of symbols that map onto the rest of the world ambiguously.
