Evaluation of Effective Demographic Variables in Competition Performances of Turkish Wrestling Referees using Logistic Regression Analysis

Abstract

The aim of this study is to evaluate the effective demographic variables on their competition performances of Turkish wrestling referees through logistic regression analysis. The research data consist of demographic variables and the referee evaluation reports of the year 2016. The referees were classified as successful and unsuccessful according to their performance scores. Logistic regression analysis was used to assess the factors affecting the performance of the referees. In order to determine the successful referees according to established model, it has been determined that in a competition international referees are 49 times more successful than the national referees; the referees who have >6 years of experience are 9 times more successful than the referees who have ≤6 years of experience; the referees who wrestle in international level are 6 times more successful than the referees who do not wrestle and who do wrestle at the national level; referees to gain social identity, referees to doing as hobby, and referees doing for other reasons are 6, 39 and 22 times more possible, respectively as compared to referees to gain social status; 31-40 age referees and ≥41 age referees are 7.9 and 24.9 times more successful than ≤30 age referees, respectively. As a result, if a successful referee performance is desired, referees who have wrestled internationally in the past and who are ≥41 years of age and international referees who are refereeing for hobby or other reasons should be selected.
