Abstract
The size of national team market values and their effect on results achieved at the 2018 Football World Cup in Russia is examined for determination dependency. The size of the team market value is determined by the sum of the market values of all players on the team.The total market value of teams is then related to their success (or failure) at the World Cup, which is expressed by the total number of points earned.
The results of the correlation and regression analysis show moderate influence of market value on results achieved at the 2018 World Cup. The correlation coefficient was 0.57.
The distance from the regression line represents the deviation from the regression to the predicted result,and establishes a resulting effectiveness value for each team. The Croatian team was the furthest away from the regression line, thus is considered to be the most effective team relative to its market value.
The least effect team was Germany. The results are compared with previous top football event results.
