LLM prompt evaluation needs statistical significance and effect size

A recent article on dev.to proposes a more rigorous method for evaluating large language model (LLM) prompts, moving beyond simple average score comparisons. The author argues that small datasets commonly used for LLM evaluations are insufficient for reliable average scores, and that statistical significance is crucial. The piece advocates for the Mann-Whitney U test over the t-test due to its non-parametric nature, and also emphasizes the importance of effect size metrics like Cohen's d to ensure practical meaningfulness alongside statistical significance.
