Description
This programme follows from the programme previous to it. D203/12 consisted largely of two filmed interviews by students of small businessmen. This programme is a discussion of such student intervi...ews in terms of their validity and reliability. The programme is divided into two sections. The first part consists of four students discussing their interview experiences and the way in which these experiences affected the reliability and validity of the interviews. There is a discussion of the many variables that might affect an interview situation, to what extent the structure and performance of the interview produced relevant information and what devices can be used to improve the validity. Filmed examples are taken from D203/12 to highlight the points discussed in this programme. The second part of the programme is a discussion between two authorities on research methods, Dr. Tony Bates of the Open University and John Wakeford of Lancaster University, on how these student interviews differed from those administered by professional researchers.

| Footage description: | After two sequences from the student interviews shown in the previous programme (D203/12) John Ballard introduces the programme. It will deal with the concepts of validity and reliability of the information gained at interview. Using examples from the interviews shown in part in D203/12 John Ballard first discusses the question of variables in the interview situation which affect the reliability of interview results The students in the studio with John Ballard add their comments. Ballard now turns to the question of whether the interviews produce valid and relevant information. Sequences from Howison's interview with Farr are shown as examples of how information may be supplied indirectly, and as examples of how a questionnaire may be designed such that one question is backed up by a second or third question in order to obtain complete information on one point. John Ballard now considers the question of how the validity of question responses can be improved. The question is discussed by Ballard in company with the students in the studio. A sequence showing Farr discussing the interview with Ballard is first shown. Ballard now discusses with the students the question of the validity of the interview as a whole. This is discussed by Ballard and the students with him in the studio. John Ballard now introduces John Wakeford and Tony Bates with whom he begins a discussion on the reliability of the interview sample. John Wakeford points out certain differences between the sampling methods employed by the students and the more normal precise definition of sample parameters. Tony Bates replies to the criticism, outlining the main purpose of the student exercise. Wakeford poses other questions and makes other comments in reply to which Tony Bates clarifies the main aims of the student exercise. Bates, Ballard and Wakeford now discuss the nature and construction of the questions in interview questionnaires, and the weight that one can assign to these questions. Ballard asks about possible other methods of obtaining information on the subject other than interviewing. Ballard closes the programme. Credits. |
