Interpreting Statistical Findings

This study examines the relationship between test time and BDI scores in a group of individuals not receiving treatment. Descriptive statistics and tests of within-subjects effects are used to analyze the data. The results support the hypothesis of improvement in BDI scores over time with no intervention. Pairwise comparisons show no significant differences in BDI scores between test times. Regression analysis is also conducted to explore the relationship between optimism, physical exercise, and BDI scores.
