*6.4. Sports Events from the Poznan Half Marathon Cycle Cause an Increase in Crime in the City (e.g., Thefts)*

Checking if the fractions of the people who answered YES to this question differ significantly between the two analyzed groups—Chi-square test. Fractions do not differ from each other in a statistically significant way: *p*-value = 0.362 (>0.05). It cannot be assumed that there is a relationship between the type of event and the answer to the question being analyzed. The distribution of the analyzed feature in both groups again differs significantly from the normal (*p* < α), therefore the nonparametric test was used—U Mann Whitney's test. The average level of dissatisfaction is not significantly different between the analyzed groups *p* = 0.971 (the average in the samples was: for the Half Marathon 3.28, for Cavaliada - 3.31).
