This assignment demonstrates the analysis of shop sales data using SPSS, focusing on the relationship between product categories and profit totals. The analysis includes the use of GGRAPH to create visualizations such as bar charts and line graphs illustrating mean and sum of profit for each product category. Additionally, a decision tree is constructed to predict product categories based on profit totals, and ONEWAY ANOVA is performed to compare the means of profit totals across different product categories, with post-hoc tests (Tukey HSD) to identify significant differences. The analysis provides descriptive statistics, tests for homogeneity of variances, and multiple comparisons to gain a comprehensive understanding of the factors influencing shop sales and profitability. The document also includes syntax and notes generated by SPSS during the analysis process.
