APSY2216 Final Flashcards
(14 cards)
sampling in mixed research: time orientation
concurrent and sequential
identical sample relation
2 samples that are the same
parallel sample relation
2 samples that are similar because both are drawn from the population of interest
nonparallel sample relation
2 samples from different populations (ex: moms of newborns, moms who gave birth a year ago)
nested sample relation
smaller sample from within your original sample; most widely used
multilevel sample relation
same population, but different levels (ex: administration and teachers / general info and more specific experience)
exploratory design
QUAL -> QUAN
explanatory design
QUAN -> QUAL
triangulation design
QUAL + QUAN
longitudinal study: trend
independent samples taken from a population over time; the same questions are asked
longitudinal study: cohort
different samples from a population whose members do not change, any group of people with a common classification or characteristic
longitudinal study: panel/prospective
the same individuals are studied at successive points over time
reasons for total nonresponse
refuse to be interviewed, not at home when the interviewer calls, unable (e.g. illness, inability to speak the language), cannot be located
reasons for item nonresponse
does not know the answer, finds certain questions embarrassing/irrelevant, pressed for time, unclear or illegible answers
