Study Notes
Methods of Collecting Qualitative Data
- Focus Group: an open discussion group of 6-8 participants led by a neutral moderator or facilitator.
- Observation: gathering open-ended, firsthand information by observing an object or phenomenon.
- Interview: a purposeful discussion between two or more people by asking questions directly from respondents, either face-to-face or by telephone.
- Archival Materials: using materials such as newspapers.
Types of Qualitative Data
- Nominal data: involves naming or identifying a thing without assigning it to an implicit or natural value or rank.
Methods of Collecting Quantitative Data
- Survey: collecting information from a group of people by employing printed questionnaires mailed to large samples, or through the telephone.
- Experiment: deliberately assigning subjects to various treatments for studying the reasons for changes in the output response(s).
- Observational Study: collecting data in a way that does not directly interfere with how the data arise.
Types of Quantitative Data
- Discrete data: reflects a number obtained by counting, typically involves integers.
- Continuous data: can be divided and reduced to finer and finer levels, with the number of decimal places depending on the precision of the measuring device.
- Interval data: specifies the exact differences between the values, in addition to classifying and ordering the measurements.
- Ratio data: tells us the exact value between units and also has an absolute zero.
Data Validity
- The validity of results rests on the validity of the input data.
- Potential pitfalls in acquiring input data include manipulation of data to make it look "good and clean".
- Accounting data is usually sensitive and not open for public research, hence, it can be hard to obtain.
Experimental Designs
- Observational study: collects data without directly interfering with how the data arise.
- Experiment: deliberately assigns subjects to various treatments for studying the reasons for changes in the output response(s).
