A multiple-choice test created by a teacher to assess how well his/her students learned the material covered throughout the semester.
While selecting a test to use in his private practice, Kent discovered that a particular test was not very consistent or stable over time. In other words, a test-taker's score varied each time he or she took it. Kent can most likely infer that:
The Interview Research Method. Interviews are different from questionnaires as they involve social interaction. Unlike questionnaires methods, researchers need training in how to interview (which costs money). Researchers can ask different types of questions which in turn generate different types of data . For example, closed questions provide ...
Interview Design. Quite often interviews will be recorded by the researcher and the data written up as a transcript (a written account of interview questions and answers) which can be analyzed at a later date.
2. Unstructured interviews generate qualitative data through the use of open questions. This allows the respondent to talk in some depth, choosing their own words. This helps the researcher develop a real sense of a person’s understanding of a situation.
A structured interview is a quantitative research method where the interviewer a set of prepared closed-ended questions in the form of an interview schedule, which he/she reads out exactly as worded. Interviews schedules have a standardized format which means the same questions are asked to each interviewee in the same order (see Fig. 1).
The Interviewer Effect. Because an interview is a social interaction the appearance or behavior of the interviewer may influence the answers of the respondent. This is a problem as it can bias the results of the study and make them invalid.
1. Group interviews generate qualitative narrative data through the use of open questions. This allows the respondents to talk in some depth, choosing their own words . This helps the researcher develop a real sense of a person’s understanding of a situation. Qualitative data also includes observational data, such as body language and facial expressions.
Group interviews are less reliable as they use open questions and may deviate from the interview schedule making them difficult to repeat. 2. Group interviews may sometimes lack validity as participants may lie to impress the other group members. They may conform to peer pressure and give false answers.
