Study Notes

Types of Interviews

Personal, telephonic, structured, unstructured, individual, group, clinical, and selection interviews are identified.

Indirect/Questionnaire Method

Questionnaires are self-administered, can be distributed by mail or in group settings.
Require respondents to read and write answers, thus necessitating clear design to ensure reliability.

Types of Questions

Open-ended questions: Do not provide response categories, ideal for subjective data.
Closed-ended questions: Include pre-defined response options, suitable for objective data.

Data Collection

Defined as gathering and measuring information systematically to answer research questions and assess outcomes.
Poor planning can render data sets useless for intended research purposes.

Steps in Data Collection

Set clear objectives for data collection.
Identify necessary data based on objectives.
Choose appropriate data gathering methods and define collection points.
Design necessary data gathering forms.
Implement data collection.

Sources of Data

Primary Data: Collected firsthand, original, provides direct insights, e.g., surveys or experiments.
Secondary Data: Previously collected data by others, passed through analysis, interpretive in nature.

Primary Data Collection Methods

Direct/Interview Method: Involves oral communication, direct interaction for information gathering.
Indirect/Questionnaire Method: Uses self-administered questionnaires for data collection.
Experiment: Involves direct human intervention to observe effects on variables.
Observation: Systematic watching and recording of behavior or events.

Key Design Principles of a Good Questionnaire

Keep the questionnaire concise.
Choose between open-ended or closed-ended formats.
Formulate questions clearly and logically.
Avoid leading questions that may bias responses.
Include instructions for respondents and pre-test questions before the survey.

Experiment Method

Direct human intervention to influence variable outcomes; includes participant and non-participant observer roles.

Secondary Data

Readily available data from external sources, quicker and cheaper than primary data.
Collectible through internal reports, published articles, financial data, institutional records, and official publications.

Evaluation of Secondary Data

Availability: Ensure data is accessible for research needs.
Relevance: Data must align with the research problem, considering measurement units, concepts, and currency.
Accuracy: Review the methodology, margin of error, and source reliability for data credibility.
Sufficiency: Verify that adequate data is available for analysis.
