Methods of Observation, Interviews, and Interview Schedules

1. Observation Method

Meaning; Observation is the systematic watching, listening, and recording of behaviors, events, or conditions in their natural or controlled setting.

• It is one of the oldest and most direct research tools.
• Helps when respondents cannot express themselves clearly or when researcher wants real, first-hand data.

Types of Observation

• Participant Observation: Researcher becomes part of the group being studied. Example: An extension worker joining farmers in the field to study adoption of new techniques.
• Non-Participant Observation: Researcher does not participate; only observes. Example: Researcher watching classroom teaching without joining.
• Controlled Observation: Done under pre-arranged or experimental conditions.  Example: Studying behavior of farmers in a demonstration plot.
• Uncontrolled/Natural Observation: Takes place in natural settings without control. Example: Observing how farmers interact during a village meeting.

2) Interview Method

Meaning: An interview is a verbal conversation between interviewer and respondent to collect relevant information.

• It allows probing, clarification, and deeper understanding.
• Widely used in extension, social, and educational research.

Types of Interviews

• Structured Interview: Standardized questions, fixed order. Example: Census surveys.
• Unstructured Interview: Flexible, conversational, open-ended. Example: Exploring women’s perceptions of extension services.
• Semi-structured Interview: Combines fixed questions with open-ended discussion.
• Personal Interview: Face-to-face interaction.
• Telephone/Online Interview: Fast, economical, useful for distant respondents.
• Focus Group Interview: Interview with a group to generate interactive discussion.

3) Interview Schedule

Meaning: An interview schedule is a pre-planned, written list of questions prepared by the researcher, used by the interviewer to collect data.

• It is an instrument/tool, not a method.
• Respondent’s answers are recorded by the interviewer, unlike questionnaires which respondents fill themselves.

Characteristics

• Contains both open-ended and close-ended questions.
• Questions arranged logically.
• Pre-tested before use.
• Suitable for illiterate or rural respondents.
