Physics Olympiad is a worldwide competition, held in Slovakia for the 58th time this year. The method used to distinguish between the performances of Physics Olympiad participants is assessment of their written solutions in accordance with a scoring scheme. If the scoring scheme was proposed by the author of physics problem correctly, scores of Physics Olympiad participants would be independent random variables. Assessed solutions were analyzed by analytical tools (such as Pearsońs correlation coefficient) to prove that random variables, in fact, are not independent. In this paper we focused on presenting our developed method of modifying original scores to get independent random variables and analysis of its consequences on scores. Its possible utilization to identify those assessments where Physics Olympiad participants could be overestimated or underestimated is also discussed.
