Data are from Cesare, Tannenbaum, and Dalessio (1990). "Interviewers' 
decisions related to applicant handicap type and rater empathy," Human
Performance, 3(3):157-171. This study explored how physical handicaps
can affect perceptions employment qualifications. Five videotaped 
interviews were prepared.  The applicant and the employer in each case 
were the same two male actors. In each video, the applicant appeared
with a different handicap: none, amputee, crutch user, hearing impared,
wheelchair bound. The interview proceeded with a set script which was
designed to show an applicant with average qualifications for the job.

70 undergraduate students at a large university were randomly assigned
in groups of 14 to view the tapes (one tape per group). After viewing, 
each student rated the applicant on an Applicant Qualification Scale 
(scale of 1 to 10).

Data are coded as:  0 = no handicap
                    1 = amputee
                    2 = crutch user
                    3 = hearing impared
                    4 = wheelchair bound

Data were reproduced in "The Statistical Sleuth" by Ramsey and Schafer (1997).
