The Harpp-Hogan index
Some readers may already be aware of something which quickly became apparent to me: efforts to measure cheating have been going on for a very long time. Frary (1993) reviewed cheating indices dating back to the late 1920s, following their development up to the early 1990s.
Frary himself has worked with colleagues to develop cheating detection indices (Frary, Tideman, & Watts, 1977; Frary & Tideman, 1997), and these are very much still in use today–the Integrity system2 is onesoftware package which features Frary et al.’s detection indices, as well as others.
Wesolowsky (2000) recommended a modification of the Frary et al. indices which he suggested “has a more intuitively appealing form, and exhibits more consistency with respect to certain other constraints”. I was attracted by these comments, and decided to begin Lertap modifications by basing them on Wesolowsky’s work.
