Document Summary
Levels of measurement: nominal -variable that has different categories, separate categories, cannot be ordered, ordinal - separate categories that can be ordered, distances between categories cannot be precisely measured. Interval - categories are separate, ordered and measurable ratio: same measurement as interval, but with absolute zero possible: height is interval, cannot be ratio, no-one can be 0 height, ratio - has absolute zero. From bottom to top - noir - nominal, ordinal, interval, ratio. Operationalization exercise: education - how many years of education do you have? - interval ratio try to operationalize the following concepts: On a scale 1(i don"t feel very educated) 5 (i feel very educated), where do you. What is your highest level of education obtained? . How many years did you take to nish education? : socioeconomic status. Research approach: deductive - testing theory thorough data collection and analysis, nomothetic - provides generalizable conclusions about the population.
