5 Written Questions
5 Matching Questions
- cross sectional survey
- deductive reasoning
- 5 types of prob sampling
- sampling error
- a simple how one goes about conducting the research at hand. manner of the research procedure. ex: experimental research, qualitative, historical, etc. usually logical, orderly systematic way. TOOL of scientific investigation
- b 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)
- c collect info and date from a sample of the target market or respondents during a single point in time. compare the relationships among a set of important variables based on respondents characteristics. cannot note shift in opinion.
- d 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.
- e calculate the degree that the sample might differ from the population. larger sampling error, less likely sample possesses characteristics similar to the population
5 Multiple Choice Questions
- email, web based, on cite stations. samples do not typically represent target population- usually from email list. internet most frequent in urban and higher income and education. inexpensive and quick to collect info. self administered, must be simple
- self- administer response, can have texts and graphics, skipping/ no skip software. respondents are available, not true sample of pop. software can restrict those who participate
- survey method that includes all of the members of a population. no sampling procedures and no generalizability issues
- 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
- nonprobability, prelime stages, conduct where large # of ppl congregate. not random, only can conclude if population is homogenous- like tast tetss
5 True/False Questions
inductive analogies → makes general conclusions based on individual observation
quota sampling → identified specific characteristics of a population that match quite well with purpose of the research. why someone purchase a product. oly qualified respondents
methodology bias → study and analysis of various methods. have principles that determine how the tools are deployed and interpreted
probability (scientific) sampling → randomly selected samples of units from a population. each member of the target pop has a known chance of being selected. clearly defined selection procedures and sampling error can be determined.
in home interviews → longer, open ended, scheduled appointments, challenging for interviewer but flexible, can observe, locate appropriate respondent, quality data, . just as effective as phone.
