final exam Flashcards
- uncontrolled, subjective, observational
- low reliability, high validity, inductive, in-depth
qualitative research
- controlled, objective, systematic
- reliable, valid, deductive, generalizable
- precise measurement of something
quantitative research
using multiple methods
triangulation
pros: best quality, high response rate, expansive
cons: expensive, slow turn around
personal interviews
pros: fast turnaround, relatively inexpensive
cons: low contact rates, cell phones, short
phone surveys
pros: inexpensive, expansive
cons: respondent control, slow, screeners
mail survey
pros: inexpensive, very fast, no data needed
cons: very low response rates, duplicate respondents
online survey
the process if selecting some elements from a population to represent the population
sampling
all elements about which we wish to make some inferences
population
a list of elements in the population from which the sample is actually drawn
sampling frame
a count of an element in a population
census
result from mistake in selection process or determining sample size
sampling error
can occur at any stage of the research process
non sampling error
controlled, randomized
- each unit in the defined target population has a known probability of being selected
probability
no equal chance of being in the sample
non probability
probability of selection = sample size / population size
simple random sampling
- random starting point
- skip interval
systematic sampling
- segregate population into identifiable subdivisions
- randomly select within each subdivision
stratified random sampling
randomly select groups, not individuals
cluster sampling
third option: no opinion/ dont know
dichotomous
