**5. Data Analysis**

When determining the number of recipients, information from the organizers on the expected number of participants in the event was used to make the sample selection in a way that ensured the best possible representativeness of the results obtained. The scheme of simple random sampling without replacement was used. In calculations the formula for sample size for finite population was used. The assumption was made that the maximum error of estimate (e) at 95% confidence level should not exceed 4%.

Descriptive statistics (percentages, means and standard deviations) were calculated. In order to further analyze the obtained result, respondents were asked to define the intensity level of the inconvenience associated with the organization of a sporting event in their city on a 10-point Likert scale (Table 3, Table 4, Table 5). The differences between responses were tested among the groups with a Chi-square test for independence. Statistical significance was set at *p* < 0.05. When the distribution of the analyzed feature in both groups differed significantly from the normal (*p* < α), therefore the nonparametric test was used—U Mann Whitney test. All statistical analyses were conducted using Statistica Software 10.0 (StatSoft Inc., Cracow, Poland, 2011).
