- external validity
- cost per return
- sampling unit
- intercept surveys
- a if a result can be PROJECTED to a larger external population. ex: college student findings cannot be projected onto the entire pop
- b structured, solicit info from randomly selected participants in a public place. lots of data, low cost, short period of time. volunteer sample so not generalizable and not really random. key locations- mall, airports. can get participants who fit a category. short and to the point questions
- c validity of generalized statements based on limited research studies, or implications. usually when a study in a lab is moved out of the lab causes problems, or a small ground finding in ny, can differ from ca
- d determined based on the return rate of target pop, and the value of the info provided by the respondent. is that value of the info you recieve worth the cost?
- e individual member selected from sampling frame, provide the data. primary sampling unit= household, secondary sampling unity- 30-40yr old males within each household
5 Multiple choice questions
- longer, open ended, scheduled appointments, challenging for interviewer but flexible, can observe, locate appropriate respondent, quality data, . just as effective as phone.
- when a study is repeated, and arrives at the same results. extent of which results will be consistent or replicable if the research is conducted a # of times
- compare the relationships among a set of important variables at intervals. doesnt have to be same people.
- list of the people you select for your sample
- extent to which the research really studied what it was supposed to. did it find out what it was trying to?
5 True/False questions
5 types of prob sampling → simple random sampling (name in bucket)
systematic random sampling (units from pop based on skip interval)
stratified sampling (from a subset of homo pop)
oversampling (more than 1 pop, want more sampling)
inductive reasoning → something known to be true (major premise), through a supporting idea or rule (minor premise) to the conclusion. ex: all ad is paid more, see an ad, assume its paid for.
census → survey method that includes all of the members of a population. no sampling procedures and no generalizability issues
purposive sampling → like stratified sampling, not random. most common form of nonprobability. must complete a quota for each strata- like 40 blacks, etc.
statistical syllogism → similarities between two things to a conclusion about some additional attribution of both things.
