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).
