Document Summary

Numbers, measures and words: families of numbers, counting vs. measuring, numbers vs. numeerals. *** measures: construct, indicator, score, scoring method, range of convenience, issues of representativeness and relevance, schematic diagrams. Words: structure of a word, phoneomic ambiguity, lexical ambiguity, garden path effect. Numbers: different families of numbers, natural numbers (cid:1005), (cid:1006), (cid:1007) , whole numbers (cid:1004), (cid:1005), (cid:1006), (cid:1007) . Irrational numbers does not end or repeat a sequence of digits (i. e. , pi- (cid:1007). (cid:1005)(cid:1008)(cid:1012)(cid:1009)(cid:1013)(cid:1006)(cid:1010) (cid:895: used for measuring. Numerals and numbers are different: decimal numerals (0,1,2,3,4,5,6,7,8,9, hexidecimal numberals (0,1,2,3,4,5,6,7,8,9,a,b,c,d,e,f, roman numerals, sometimes, numerals are not numbers at all (i. e. licence plate, numbers on the back of sports jersey) Measurement: construct is a conceptual continuum that describes our experiences of the world (i. e. happiness) Indicator is a feature of the world used to represent a given construct (i. e. tears = someone is sad) mental things. Two important issues in measurement: representitiveness and relevance.
