Comparative Analysis of Treatment Groups Using SPSS

Category: Data Analysis / Biostatistics

Tools Used: SPSS (Nonparametric Tests, ANOVA, Post Hoc Comparisons)

Description:

Conducted statistical analysis of treatment groups to evaluate differences in body weight and liver weight across multiple conditions (Control, Commercial, Bacilli, Mixed). Tasks included:

Preparing case processing summaries with complete and missing data checks

Applying nonparametric tests across weekly measurements

Performing one‑way ANOVA to compare liver weights between groups

Running Bonferroni post hoc tests to identify significant differences

Key Findings :

Body Weight: All groups had complete data (N=30 each).

Liver Weight: Significant differences observed between groups (F=16.42, p<0.001).

Post hoc analysis showed the Mixed group had significantly higher liver weights compared to Control and Commercial groups.

Results highlighted the importance of treatment type in influencing physiological outcomes.
