Research Methods 1
| Question | Answer |
|---|---|
| Operational definition | based on how concepts are measured |
| Conceptual definition | dictionary definition |
| Descriptive research | describe patterns |
| Correlational research | relationship between variables |
| Experimental research | cause and effect, IV and DV |
| Quasi-experimental research | cause and effect of naturally occurring events |
| Systematic empiricism | systematic observations, repeatable measurement procedures |
| Variability | measures differ from each other |
| Descriptive stats | summary |
| Inferential stats | draw conclusions |
| Variance | avg deviation from mean |
| Total variance | ignores group factors, includes all groups |
| Systematic variance | considers group factors, difference between groups |
| Error variance | doesn't consider group factors, includes only 1 group |
| Effect size | ability to make impact, proportion of variance that is systematic |
| Meta-analysis | study of studies (combines effect sizes) |
| Observational measures | overt behavior |
| Self-report measures | subject reports own behavior, uses interval scale |
| Physiological measures | physical response |
| Converging operations | combination of measures |
| Categorical data | labels |
| Nominal scale | categorical, categories |
| Ordinal scale | categorical, categories in order |
| Continuous data | numbers |
| Interval | continuous, numbers without 0 |
| Ratio | continous, numbers with 0 |
| Measurement error | due to unrelated factors; transient states, stable states, situational factors, measure characteristics, mistakes |
| Observed score | true score + measurement error |
| Transient states | temporary (anxiety) |
| Stable states | near-sightedness |
| Situational factors | environment (online exam) |
| Measure characteristics | multiple choice exam vs free response |
| Reliability | consistency of measurement; inter-observer, test-retest, interitem |
| Inter-observer | observer agreement on measure |
| Test-retest | independent measures similar |
| Inter-item | independent items measured similarly |
| Validity | instrument acurately measures what it intends to (BMI vs creativity not valid); criterion, concurrent, predictive |
| Criterion-related validity | ability to distinguish between individuals of different categories (depressed vs not depressed) |
| Concurrent validity | symptoms and diagnosis |
| Predictive validity | ability to accurately predict outcome` |
| Probability sample/simple random sample | participants have equal probability of being randomly chosen |
| Power | ability to detect effects |
| Stratified random sample | each strata randomly sampled |
