💡Tips & Knowledge
- •A p-value < 0.05 is commonly used as the threshold for statistical significance (5% level)
- •Understand the trade-off between Type I error (false positive) and Type II error (false negative)
- •Statistical significance ≠ practical importance. Never judge by p-value alone — also consider effect size
