In 1999, the International Volleyball Federation (IVF) changed
the scoring system of volleyball, from the side-out scoring system
to the rally scoring system. The main goal of the scoring system
change was to make the length of the game more predictable. This
short paper investigates whether the change achieved its goal.
First, I use a simulation model of volleyball matches to
demonstrate that the length of the matches is more predictable in
the rally scoring system, regardless of the relative strength of
the teams. Then, I analyze data on volleyball matches from the
U.S. Women’s Northern Sun Intercollegiate Conference, and compare
the variance of the length of the matches before and after the
scoring system change in 2000 and 2001. The empirical data shows
that the length of the matches became more predictable. Also, with
the help of the simulation model, I show that the scoring system
change does not significantly affect the outcome of the matches.

Álvaro,
Tenho curiosidade em conhecer o teor do trabalho científico a respeito do tema. Infelizmente não tenho conhecimento da língua inglesa. Seria possível dar uma versão tupiniquim do texto?
