2.4 Data analysis
Descriptive statistical analysis was applied to de-scribe the characteristics of beef buffalo and beef cattle
production systems. The analysis of variance (ANOVA)
was used to analyze the metric data and to determine
differences between beef buffalo and beef cattle farms as
well as differences between small-, medium- and large-scale herds, whereas the Fisher’s Exact and Chi-square
tests were applied for the categorical data. The Pear-son correlation analysis was used to describe the rela-tionship between variables. The data were analyzed us-ing the Statistic Package for Social Sciences SPSS-PC
(SPSS Inc., 1999).
