Task 1: The University of Sussex is constantly seeking to employ the best people possible as lecturers (no, really, it is). Anyway, they wanted to revise a questionnaire based on Bland’s theory of research methods lecturers. This theory predicts that good research methods lecturers should have four characteristics: (1) a profound love of statistics; (2) an enthusiasm for experimental design; (3) a love of teaching; and (4) a complete absence of normal interpersonal skills. These characteristics should be related (i.e., correlated). The ‘Teaching of Statistics for Scientific Experiments’ (TOSSE) already existed, but the university revised this questionnaire and it became the ‘Teaching of Statistics for Scientific Experiments – Revised’ (TOSSE–R). They gave this questionnaire to 239 research methods lecturers around the world to see if it supported Bland’s theory. The questionnaire is in Figure 17.9, and the data are in TOSSE.R.dat. Conduct a factor analysis (with appropriate rotation) to see the factor structure of the data.
