Study Notes
Secondary Data
- Secondary data refers to data gathered earlier for another purpose, not specifically for the current research project.
Advantages of Secondary Data
- Can be found quickly and cheaply.
- Can provide comparable information to primary data, such as census reports and industry statistics.
- Allows for extended time and space range, making it suitable for research on past events.
- Can be used to gather data on distant places, such as foreign countries, at a lower cost.
Disadvantages of Secondary Data
- Information may not meet specific research needs, as it was collected for another purpose.
- Units of measurement may not match.
- Different time periods may be involved.
- Accuracy of the information may be difficult to assess.
- Data may be partially obsolete by the time it becomes available.
Characteristics of Secondary Data
- The researcher must be careful when using secondary data and ensure it meets the following characteristics:
- No further information is provided.
Methods of Data Collection and Design of Data Collection Forms
- Sources of data can be grouped into two types: primary and secondary.
- Primary data is developed or gathered by the researcher specifically for the research project.
- Secondary data has previously been gathered by someone else and/or for another purpose.
Classification of Data
- Data can be classified according to attributes or class intervals.
- Attributes refer to descriptive characteristics, such as gender or occupation.
- Class intervals refer to numerical characteristics, such as income or age, which can be measured through statistical units.
Data Analysis
- Data analysis involves transforming processed data to find patterns and relationships among data groups.
- Analysis involves computing certain indices or measures and searching for patterns or relationships among data groups.
- Analysis can be categorized into descriptive analysis and inferential analysis.
Descriptive Analysis
- Refers to the study of the distribution of one variable.
- Involves transforming raw data into a summary format to make it easy to understand and interpret.
