Andrei 11 Naonal Instute of Stascs Romania, RomaniaIn chess there is a rang(ELO) indicang the players’ strength.The Internaonal Chess Federaon (FIDE) uses analgorythm to calculate the ELO rang. Some players or some observers of the chess phenomenon aren’t happywith the way it is calculated now and have launched a campaign to change the method of determining ELOrang. To achieve this goal, they need a survey to demonstrate the approval of the chess community regardingtheir proposal. My opinion is there is some need of changing the way ELO rang is calculated, as there aresome cases in which it doesn’t actually reflect the performances of a player. The stascal series demonstratethat in the last years, there is a trend of concentraon of the rang around certain values(for example 2400 or2700)...2.1.2 The Failure of the Half-Open Interval Missed Housing Unit ProcedureS. Eckman 2 , C. O’Muircheartaigh 11 University of Chicago, United States; 2 Instute for Employment Research, GermanyThe half-open interval procedure seems to offer an inexpensive method of reducing undercoverage in housingunit frames during data collecon: units missing from the frame are linked to covered units and given a chanceof selecon. The procedure is commonly used in U.S. face-to-face surveys. This paper provides details onhow the procedure should work, and then discusses problems both in principle and in pracce. Reporng theresults of an experiment in three U.S. cies, we show that interviewers do not carry out the procedure correctly,leading to uncorrected undercoverage and the introducon of overcoverage. On the basis of this evidence, weconclude that the half-open interval procedure should not be considered a cure for undercoverage and shouldbe used only with great care and training.
