SOCI 217 Lecture Notes - Lecture 1: Ethnomethodology, Operationalization
Document Summary
Variables in question must be empirically correlated (when one moves the other moves, don"t know if it"s same direction) We often derive the characteristics of social groups from those of their individual members. *typically involves some random selection mechanism (cid:224) representative of larger population. All units in a target population not having a known non zero probability of being included in the sample. We want to see whether students in soci 217 001 prefer having a midterm exam rather than midterm paper by selecting sample of 10 people from a total of 160 students enrolled in a class. *study population: the aggregation of elements from which the sample is actually selected, based on our criteria for inclusion. Steps in using a table of random numbers in srs: take the class list and number each of the students (the members of the, determine the number of digits you need to use in your table of random numbers population)
