Research Methods #3
| Question | Answer |
|---|---|
| What are 6 step in Operationalizing a concept | 1, Conceptual definition 2, Develop item pool 3, Choose response formal 4, Collect Data 5, Item Analysis 6,Test reliability & validity |
| Is Likert Scale an ordinal or interval | it is ordinal, but often treated as interval in statistical analysis |
| To what quality criteria is systematic & unsystematic error harmfull | random error >> to reliability systematic error >> to validity |
| What are 4 methods to measure reliability | 1, Test-Retest = second test some time later 2, Parallel-form reliability = measuring same concept with two comparable function 3,Inter-item consistency reliability 4, Split-half reliability |
| How to test Inter-item reliability | with Cronbach´s Alpha = do items tend to move together |
| What are 6 types of validity | 1, Face validity 2, Concurrent validity 3, Predicitve validity 4, Construct validity 5, Convergent validity 6, Discriminant validity |
| What is 1, Face validity 2, Concurrent validity 3, Predictive validity | 1, Face validity = does the measure look reasonable at first glance 2, Concurrent validity = can this distunguish between people we know that differ 3, Predictive validity = does it successfully predict a relevant future outcome |
| What are two major components of construct validity | 1, Convergent validity = do variables correlate of theory claims to 2, Discriminant validity = do thing that arent related show a low correlation |
| What is Demarcation criterion (2) | 1, criterion to call something scientific 2, science must be falsifiable = we can test it & potentially reject |
| What are two types of non-falsifiable statements | 1, Tautologies = statement that is true by definition (Triangle has three sides) 2, Statements about unobservable phenomena = ex. God exist |
| What does 1,Rigor 2,Parsimony mean | 1,Rigor = carefull methodology 2,Parsimony = avoid unnecessaty complexity |
| What is 1,Ontology 2,Epistemology | 1,Ontology = What is reality? 2,Epistemology = How can we know about that reality? |
| What is 1,Positivism 2,Social constructionism | 1,Positivism = Social world exists externally and can be studied objectively 2,Social constructionism = Social reality is not simply objective and external |
| How does positivism research style look like (3) | 1, researcher should be independent 2,large sample & statistics 3, deductive reasoning |
| How does social constructionism reasearch style look like (3) | 1, research is part of the process 2, rich qualitative data 3, inductive reasoning |
| What is deductive & inductive reasoning | Deductive = Theory > Hypothesis > Data > Test Inductive = Data > Patterns Indetification > Theory Development |
| What is abductive reasong | start with an unexpected observation & search for the best explanation |
| What is pragmatism | producing useful knowledge for the problem than defending one of the philosofical camp |
| What are two design choices in mixed method approach | 1, Sequencing = should qual or quan be used first or both at the same time? 2,Dominance = is the study predominatly qualitative or quantitative |
