There are more types of interviews than most people think. Research interviews are different from questionnaires as they include social interactions. A research interview is commonly a qualitative research technique in which the researcher observes the behaviour and expressions of people using patterns and stories. In most cases, the interviewer intends to understand the people using a well-planned and executed series of questions and answers. Researchers can ask different types of questions for the seeking off to generate different types of data. For example, questions with a fixed set of responses and open questions allow people to express their thoughts in their own words.
Structured research interviews
A structured interview is a method of research interview that relies on asking a question in a set order to collect the data. In research, structured interviews are common in quantitative observation. They are also used in qualitative observation if the questions are open-ended, but they are less common. It is the most systemized type of research interview. Compared to unstructured interviews, the interviewer uses a planned series of questions. Asking fixed questions in a set order allows you to easily compare responses between people in a uniform context. This can help you see patterns for further research. Structured interviews are often used in job interviews and are common in marketing, social science, survey and other research fields. However, if as a researcher you are facing difficulties in developing interview questions you can get help from a PHD dissertation services. The writers of such services will guide you properly.
Note:
In a Structured interview, the topic and order of the questions are already determined.
Characteristics of a Structured Interview
- Utilize a standardized product of inquiry.
- Observes behavior and expressions using patterns and stories.
- Structured interview is easy to replicate.
- Sequential in nature.
Advantages of structured interview
Data collected from this type of research interview is easier and objective to analyze and observes the patterns. This is because the structured interview requires the relevant and brief answer to the questions unlike unstructured interview.
Also, structured interview is used to collect more information from large data of target population.
Disadvantages of structured interview
Unlike information acquired during an unstructured interview, data gathered through a structured interview lacks depth and detail. A structured interview limits the subject to a set of questions, preventing researcher from offering additional information that would be valuable in the research.
A structured interview is a less valid data gathering method, whereas an unstructured interview is a more legitimate data collection method. The researcher is not permitted to depart from the line of questioning in a structured interview, but this is permitted in an unstructured interview.
Example
Assume 100 candidates have applied for 20 openings of a content writer with an Freelancer company. They will be asked data structure interview questions. The top 30 candidates with the highest scores will move to a round of HR interview consisting of behavioral questions.
Unstructured research interview
An unstructured interview type of research interview that relies on asking participants question in order to collect the data on the topic. In unstructured interview questions are not set in pattern and not arranged in advance. In research interview, unstructured interviews are usually in qualitative observations, and very helpful in social science focusing on personal experiences. Unstructured interviews are very informal and flexible, particularly useful for exploratory research tool. Comparing with structured interviews, questions are not set in the order in which they are presented. These are open-ended. This lack of setup can help a researcher to collect detailed information on the topic, while still allowing you to observe patterns in the analysis stage.
Note
Unstructured interviews are very different from other types of interviews as in these types of interviews questions are not setup in order and topic.
Characteristics of an Unstructured Interview
- Unstructured interview is more flexible and comfortable to conduct.
- It relies on spontaneity in its method of inquiry.
- This type of research interview is a method of qualitative research.
- Descriptive in nature.
Advantages of unstructured interview
An unstructured interview type of research interview use to gather information on complex issues. This is because unstructured interview creates a detailed discussion on the topic between the interviewer and participant which allows the later to reveal important information.
Also, unstructured interviews are more comfortable than structured interviews. In unstructured interviews interviewer has the opportunity to create more questions on the basis of information provided in the discussion, unlike a structured interview that follows a strict sequence.
Disadvantages of unstructured interview
When opposed to a structured interview, an unstructured interview takes more time. An unstructured interview requires more time and resources than a structured interview that follows a sequence since it is not limited to specific questions or a sequence. In contrast to a structured interview, which collects the most relevant responses, an unstructured interview creates enormous amounts of data that is difficult to categories and analyse. An unstructured interview, unlike a structured interview, is regard unreliable and highly subjective because it is not standardised.
Example
Consider a company announces a job vacancy for manager and 10 people apply for this job. The interviewer asks different questions with different participant. The difficulty and subject of questions will change depending on the depth of knowledge of the candidate.
Conclusion
Both structured and unstructured interviews are types of research interviews that are used independently in research. Structured interview allows you to collect quantitative research data, while unstructured interview allows you to collect qualitative research data. This serves as the basis of further research.
Structured interviews are easy to replicate because these interviews use arrange setup of questions with brief and relevant answers. On the other hand, unstructured interviews are more comfortable and flexible because questions are not determined and it allows free hand discussion between researcher and interviewee. Generate interview questions based on the responses provided by the research subjects. One-on-one conversations are the most common means of conducting an unstructured interview. On the other hand, a structured interview can be conducted through one-on-one interviews or through other methods like surveys and questionnaires.
