Document Summary
Midterm and quizzes will be textbook stuff: but the final will be more applying concepts. Chapter 1: standardization: measures exact same thing in different cultures, countries, sex, basically everything. Chapter 4: nominal scale, people usually respond honestly/more to what year they were born than their age, ordinal scale. Interval scale (strong): ze(cid:396)o does(cid:374)"t (cid:373)ea(cid:374) a(cid:271)se(cid:374)(cid:272)e of a(cid:374)ythi(cid:374)g: likert scales are ordinal, but we treat them as an interval scale, ratio scale (strong): absolute zero. Nominal scale: uses names to classify individuals, e. g. girl vs. boy, e. g. art vs. biology vs. business, do not measure size or direction of different variables, no quantitative information. Ordinal scale: set of categories that are ranked in terms of size or magnitude, e. g. 1st, 2nd, 3rd: directional relationship, do not determine size of difference, e. g. doesn"t say how much slower the 2nd car in the race was. Ordered categories that are all spaced exactly the same size.
