The University of Sussex constantly seeks to employ the best people possible as lecturers. They wanted to revise the ‘Teaching of Statistics for Scientific Experiments’ (TOSSE) questionnaire, which is based on Bland’s theory which says that good research methods lecturers should have: (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 University revised this questionnaire to become the ‘Teaching of Statistics for Scientific Experiments – Revised’ (TOSSE–R; Figure 18.18). They gave this questionnaire to 239 research methods lecturers to see if it supported Bland’s theory. Conduct a factor analysis (with appropriate rotation) and interpret the factor structure (tosser.sav).

I once woke up in a vegetable patch hugging a turnip that I'd mistakenly dug up thinking it was Roy's largest root 2. If I had a big gun I'd shoot all the students I have to teach 3. I memorize probability values for the F-distribution 4. I worship at the shrine of Pearson 5. I still live with my mother and have little personal hygiene 6. Teaching others makes me want to swallow a large bottle of bleach because the pain of my burning oesophagus would be light relief in comparison 7. Helping others to understand sums of squares is a great feeling 8. I like control conditions 9. I calculate 3 ANOVAs in my head before getting out of bed 10. I could spend all day explaining statistics to people 11. I like it when I've helped people to understand factor rotation 12. People fall asleep as soon as I open my mouth to speak 13. Designing experiments is fun 14. I'd rather think about appropriate dependent variables than go to the pub 15. I soil my pants with excitement at the mere mention of factor analysis 16. Thinking about whether to use repeated or independent measures thrills me 17. I enjoy sitting in the park contemplating whether to use participant observation in my next experiment 18. Standing in front of 300 people in no way makes me lose control of my bowels 19. I like to help students 20. Passing on knowledge is the greatest gift you can bestow on an individual 21. Thinking about Bonferroni corrections gives me a tingly feeling in my groin 22. I quiver with excitement when thinking about designing my next experiment 22. I often spend my spare time talking to the pigeons... and even they die of boredom 23. I tried to build myself a time machine so that I could go back to the 1930s and follow Fisher around on my hands and knees licking the floor on which he'd just trodden 25. I love teaching 26. I spend lots of time helping students 27. I love teaching because students have to pretend to like me or they'll get bad marks 28. My cat is my only friend
