Study Notes

Types of Research Data

Primary Data: Collected by the investigator for a specific purpose.
- Examples: questionnaires, interviews, observations, case studies, life histories, action research
Secondary Data: Collected by someone else for a different purpose, but utilized by the investigator for a new purpose.
- Examples: previous research, official statistics, mass media products, diaries, letters, government reports, web information, historical data

Advantages of Primary Data

The investigator controls the data collection process, ensuring relevance to their specific research question.
Greater confidence in data quality as the investigator directly oversees the collection process.
Allows for flexibility to collect additional data if needed during the study.

Disadvantages of Primary Data

Requires significant effort in managing all aspects of data collection.
Involves ethical considerations, such as obtaining consent and permissions.
Costly to collect and analyze data.

Advantages of Secondary Data

Data is readily available, eliminating the need for data collection efforts.
Often more cost-effective compared to collecting primary data.
The investigator is not responsible for the data quality, as it was collected by others.

Disadvantages of Secondary Data

The investigator lacks control over what data was collected.
Data quality may be unknown or questionable.
Obtaining additional data or clarification is not possible in most cases.

Data Classification by Nature

Quantitative Data: Numerical information obtained using instruments like rulers, balances, and thermometers.
Qualitative Data: Descriptive information gathered using sensory observations.

Types of Research Data

Primary Data: Information gathered by the researcher specifically for their study.
- Examples: Questionnaires, interviews, observations, case studies, life histories, action research.
- Advantages:
  - Data is relevant to the research question.
  - Quality of data is controlled by the researcher.
  - Additional data can be collected if needed.
- Disadvantages:
  - Requires significant effort in data collection (design, funding, ethical considerations).
  - Ensuring high data quality is essential (accuracy, format, avoidance of bias).
  - Can be expensive to obtain.
Secondary Data: Existing data collected by someone else for a different purpose but utilized by the researcher for a new study.
- Examples: Previous research, official statistics, mass media products, diaries, letters, government reports, web information, historical data.
- Advantages:
  - Data is readily available, eliminating data collection difficulties.
  - Typically less expensive than collecting primary data.
  - Researcher is not responsible for the initial data quality.
- Disadvantages:
  - Researcher has no control over the data collection process.
  - Data quality may be uncertain or compromised.
  - Obtaining additional data or clarification is often difficult.

Data Classification by Nature

Quantitative Data: Numerical data measured with instruments (rulers, balances, thermometers).
Qualitative Data: Descriptive data observed through senses (sight, sound, smell, taste, touch).

Differences Between Qualitative and Quantitative Data

Qualitative Data: Descriptive, provides in-depth understanding, context-dependent.
Quantitative Data: Numerical, provides precise measurements, generalizable results.
