Spss for macintosh v 25

A Kolgomorov-Smirnov test was used to test the normality of the distribution of the data and it indicated that it is non-parametric. Then, results were shown as median and interquartile range.
Next, inferential analyzes were conducted, including Mann–Whitney’s U tests. Additionally, effect sizes (Cohen’s d) were calculated and can be interpreted as small (0.20 to 0.49), moderate (0.50 to 0.79) and large (d ≥ 0.80) (Cohen, 1988 ).
All data were analyzed using the statistical package SPSS for Macintosh v.25.0 (SPSS Inc., Chicago, IL, United States). A p value of less than 0.05 was considered to be statistically significant.

A Kolgomorov-Smirnov test was used to test the normality of the distribution of the data and it indicated that it is non-parametric. Then, a descriptive analysis was performed to obtain information on the number of times the categories of each study variable occurred (mean, standard deviation, median, maximum, and minimum).
Next, inferential analyzes were carried out to analyze the differences between the anxiety factors and the self-confidence with the independent variables result (winner/loser), ranking (higher/lower), seed (seeded/non-seeded), round (first round, quarter-final, semi-final, final). Mann–Whitney’s U and Kruskal Wallis’s H tests were used. A p value of less than 0.05 was considered to be statistically significant.
