Kolmogorov-Smirnov and Shapiro Wilk normality test was applied to ensure that the data conformed to the assumption of normal distribution. In order to determine the relationship between the techniques applied according to the normality of the data and the success, the "Pearson Correlation" test was applied to the data with normal distribution and the "Spearman Correlation" test was applied to the data without normal distribution in the "SPSS 25" program. A significance level of p<0.05 was used when applying the tests. While examining the significance of the variables with success, correlations were made by giving 1 value to the first team among 16 teams and 16 values to the last team. As a result of the research, a very strong and positive correlation was found between success and ace and side out percentages per set, attack percentages after medium and bad reception, and attack percentages after excellent and good reception. A strong positive correlation was found between transition attack percentages, break point attack percentages, number of blocks per set, number of points per match and success. There was a negative and strong significant relationship between the headline error per set, the offensive error per set and success. No significant relationship was found in other parameters.
