Quantitative method using a questionnaire to collect responses from respondents
Survey
Verbal question-and-answer technique eliciting qualitative data

- reliability, replicability & validity → stable measure over time, across researchers, measuring what we intend to measure
Test → repeat, statistical measures
Quantitative methods
- Triangulation: using multiple data collection techniques to gather data in the same study
-Interviews, observations s focus groups, document analyses
Qualitative methods
Investigation that relies or experimentation and systematic observation rather than theoretical speculation
Empirical methods
