PSYC 510 Exam 2 - Questions and Answers What is the transcription process? -first step in analyzing interview data -an important contributor to dependability (all dialogue must be transcribed) What is a mixed method analysis? -combination of quant & qual data What are two types of sampling? -probability: every member in study pop. has known probability of being selected for research sample -non-probability: probability of person being selected is unknown (more common type in behavioral science) What is simple random sampling? -each person in sampling frame has an equal probability of being selected -use table of random #'s to select p. -assume reasonable cross-section of study pop. What is stratified random sampling? -create quota matrix to reflect all possible combos of variables in study -> sample randomly from each cell -each cell is in proportion to its representation in the pop. What is systematic sampling? -use sampling frame -> select every nth name -con: periodicity (same characteristics appear w/ same pattern as sampling interval -> biased sample What is cluster sampling? -identify groups of ppl who meet definition of study pop. -> take random sample of the groups What are convenience/hazard sampling? -use p. based on whoever is accessible -Pro: easy to acquire p. & inexpensive -Con: researcher does not know degree to which sample represents target pop. -can be stratified using quota matrix -> quota sample *most common form of sampling What is purposive sampling? -researchers use own judgement to select membership of the sample based on research goals -frequently used in case study research (typical & critical cases) What is snowball sampling? -ppl who were initially selected as p. nominate other ppl to p. What is statistical power? -the probability not making a Type II error (i.e., concluding IV had no effect on DV, when it in fact did) -lack of power increases Type II error rate -represented by beta What is the critical effect size? -target effect size What is a coherent research setting? -one that p. experience as smooth, logical flow of events What is experimental realism? -p. becomes involved in what is happening, they take the situation seriously, it impacts them What is mundane realism? -events occurring in research setting are likely to occur in some natural setting What is a post-experimental interview? -used to uncover any ethical/ methodological problems with research & educate p. about purpose of study What are the 4 functions of post-experimental interview? -ethical: alleviate any adverse effects of research (debrief is deception was used) -educational: educate research p. about nature of research in general and the study specifically -methodological: administer manipulation checks -discovery: suggest new hypotheses What are 3 types of approaches to internet research? -Translational: adapt paper material into online study -Novel (phenomenological): research hypotheses unique to the web are tested What are some advantages of internet research? -economy & ease of data collection -available 24/7 to p. -diverse range of research p. -use data already available online (e.g., blog posts) -potential to increase validity (lack of experimenter expectancy effects & social desirability bias) -publicness of research methods What are some disadvantages of internet research?
