Complete Solutions
stratified sampling Correct Ans-divide population into sub-sets of a particular variable,
stratify for demographic variables, select randomly from each strata to get right proportions of
the population
ecological fallacy Correct Ans-making unwarranted assertions about individuals based on
observations about groups
systematic error/sampling bias is caused by Correct Ans-low response rate, imperfect
sampling frame, using non-representative sampling methods
multistage cluster sampling is useful for... Correct Ans-large target populations where
individuals are not listed
multistage cluster sampling Correct Ans-making clusters and sampling from them
pros of multistage cluster sampling Correct Ans-practical for large populations, reduces costs
cons of multistage cluster sampling Correct Ans-introduce sampling error in each stage
,when starting representational sampling... Correct Ans-define target population, construct
sampling frame
coverage error Correct Ans-a sampling error that occurs when the sampling frame isn't fit for
the target population
can you generalize results from non-representative samples? Correct Ans-no
types of non-representational sampling techniques Correct Ans-convenience sample,
purposive sample, network/snowball
convenience sampling Correct Ans-select individuals that are available
purposive sampling Correct Ans-select individuals for a characteristic
network/snowball sampling Correct Ans-select individuals who contact other similar
individuals to get them in the study..etc.
goals of surveys Correct Ans-identify attitudes and behaviors, examine relationships
between attitudinal variables measured
steps in survey research Correct Ans-establish the goals of the study, determine your sample,
construct survey questionnaire, administer questionnaire
,cross-sectional survey Correct Ans-one snapshot in time, different samples
longitudinal survey Correct Ans-multiple snapshots in time, same sample
types of longitudinal surveys Correct Ans-panel, trend, cohort
panel survey Correct Ans-same people each time, just over time
trend survey Correct Ans-different random samples from the same target population
cohort survey Correct Ans-different samples, but same group of people banded together
types of surveys Correct Ans-self-administered surveys, interview surveys, experience
sampling
types of self-administered surveys Correct Ans-mailed surveys, online or emailed
questionnaires, handouts, diaries
pros of self-administered surveys Correct Ans-easy, inexpensive, no interviewer influence,
privacy, random administration or not
, cons of self-administered surveys Correct Ans-must be self-explanatory, suffers from low
response rates
ways to increase response rates in self-administered surveys Correct Ans-inducements, make
it easy to complete, persuasive cover letter, advance mailings
limitation of online surveys Correct Ans-lack of control over randomness
how to overcome limitation of lack of randomness in online surveys Correct Ans-draw
participants from bounded population, don't open to social media
phone interviews are better than face to face because.. Correct Ans-quicker results, reduced
costs, more privacy, more efficient
phone interviews are better than self-administered surveys Correct Ans-more detail possible,
better response rate
experience sampling is good for... Correct Ans-selecting panels and for longitudinal studies
experience sampling Correct Ans-getting immediate results (ex: apple watch)
double-barreled question Correct Ans-two questions in one
