In-Depth Interviews for Qualitative Research
In-depth interviews are usually conducted face to face, as body language and facial expressions can help you understand the subject’s answers. However, skilled researchers can conduct in-depth interviews by phone, which can save time and money. The style of the interview also depends on the person conducting it. A successful in-depth interviewer listens rather than talks, follows a clear line of questioning, and uses body language to build rapport with the subject. It’s more like a conversation than a formal interview.
Focus groups
If you want to explore the underlying motivations for a particular decision, focus groups can be the way to go. They allow for in-depth analysis of the respondent’s perceptions and opinions, and they are useful in comparing responses to those of reference group members. The main disadvantage of focus groups is that they take up a lot of researcher time, as they need to spend individual time with each respondent. Focus groups, however, may be a good choice if you need to gain insight without sacrificing the accuracy of your findings.
When selecting the size of a focus group, it is important to consider the preferences of the participants. Although a few studies have reported as few as four participants, many others have had as many as fifteen. Because you cannot guarantee the attendance of participants, it is best to plan for a group size of around six to eight participants. This number is large enough to obtain a wide range of perspectives while still being small enough not to disrupt the group’s flow.
Semi-structured interviews
Semi-structured interviews are an effective means of obtaining a partial understanding of a person’s thoughts and experiences. In geography, in-depth interviews have become popular, spurring debates about meaning, subjectivity, knowledge, representation, and researcher positionality. Participants often have difficulty recalling experiences, or their ability to articulate themselves is limited. Regardless, semi-structured interviews are useful in the context of qualitative research because they are inexpensive and relatively simple to conduct.
In-depth interviews are designed to provide information and opinions. Interview guides provide a conceptual framework and ask questions that reveal both general and specific characteristics of a community. These interviews also allow researchers to reach implicit reasoning and identify values and beliefs. In-depth interviews help researchers determine topics for semi-structured interviews. These interviews help researchers analyze their data and develop a plan for further research. This article will describe some key features of semi-structured interviews.
One-on-one interviews
In-depth interviews are a type of qualitative research and can be conducted with almost any group of identified individuals. The typical number of respondents is under 100, typically in the range of 25 to 75. The duration of the interview is typically between 10 and 30 minutes. One-on-one interviews are also known as qualitative interviews, and are often more valuable than quantitative surveys. A recent study conducted by Market Street Research found that 88% of participants in an in-depth interview agreed to be interviewed in detail.
Observational research
Observational research is a form of qualitative research that focuses on the behavior of participants. It involves a variety of methods and can include unstructured conversation, written observations, and videos. In some cases, the data are illustrated with floor maps or information material. However, observational research has several limitations, such as the researcher’s inherent bias and the difficulty of replicating data. Here are some examples of the main drawbacks of this method.
Non-participant observation involves observing behaviour without interaction. In this method, the researcher becomes a member of the group and participates in the process. The researcher is usually fully visible to the group being observed. In some cases, the researcher may use a one-way mirror. This method is inexpensive and convenient, and can give a researcher first-hand information that a survey can’t.
