Insights
Symmetric Distribution
Skewness of -0.017 indicates data is fairly symmetric around the mean.
High Variability
CV = 50.4%. Data has high relative variability compared to its mean.
Quick Reference
p-value: Probability of observing data if H₀ is true. p < α → reject H₀
R²: Proportion of variance explained by the model. Closer to 1 = better fit.
Skewness: 0 = symmetric · >0 = right tail · <0 = left tail
IQR: Q3 − Q1. Robust spread measure, resistant to outliers.
