Explain Types of Questionnaires.

Questionnaires are a common data collection tool in social research, allowing researchers to gather information from respondents efficiently and systematically. There are several types of questionnaires, each with its own characteristics and uses:

1. Structured Questionnaires: These questionnaires consist of closed-ended questions with pre-defined response options, such as multiple-choice, Likert scale, or yes/no questions. Structured questionnaires are easy to administer and analyze, making them suitable for quantitative research and surveys.

2. Semi-Structured Questionnaires: Semi-structured questionnaires combine closed-ended questions with open-ended questions that allow respondents to provide detailed, qualitative responses. This type of questionnaire provides a balance between standardized data collection and flexibility in capturing diverse perspectives and insights.

3. Unstructured Questionnaires: Unstructured questionnaires consist entirely of open-ended questions, allowing respondents to provide free-form responses without constraints. Unstructured questionnaires are useful for exploring complex or sensitive topics in-depth and generating rich qualitative data, but they require more time and effort to analyze.

4. Self-Administered Questionnaires: Self-administered questionnaires are completed by respondents independently, without the presence of an interviewer. These questionnaires can be distributed through mail, email, online surveys, or self-administered paper forms, offering convenience and anonymity to respondents.

5. Interviewer-Administered Questionnaires: Interviewer-administered questionnaires are conducted by trained interviewers who read questions aloud and record respondents' answers. This method allows for clarification of questions, probing for additional information, and ensuring consistency in data collection, but it may be more time-consuming and costly than self-administered methods.
