An analysis of the winning times in World Championships in Athletics

Na vzorcu zmagovalk in zmagovalcev maratonov na svetovnih prvenstvih v atletiki, od leta 1983 do 2011, sem opravil analizo zmagovalnih časov. Zanimal me je razvoj zmagovalnega časa moških in žensk ter ali se le-ta izboljšuje ali slabša. Analiza teh prvenstev je bila opravljena tudi za starost tekmovalk in tekmovalcev, pri čemer me je zanimalo, ali se le-ta pri tekačicah in tekačih zvišuje ali znižuje.An analysis of the winning times was conducted based on the sample of marathon winners (males and females) in World Championships in Athletics from 1983 to 2011. I was interested in progress of the winning time of men and women, i.e. whether the time has been improving or getting worse. An analysis of the abovementioned championships was done also for the age of competitors, with a particular interest to whether their age has been increasing or decreasing
