What is Statistical Significance?
Understanding Statistical Significance in E-commerce
Quick Definition
Statistical significance is a mathematical measure that determines whether research results are likely due to genuine effect or random chance. In e-commerce and testing, it indicates the probability that observed differences between variants are meaningful and not caused by sampling error, typically requiring a 95% confidence level.
Understanding Statistical Significance
Core Concept
Statistical significance helps researchers and marketers distinguish between genuine insights and random variations. In e-commerce testing, it prevents making critical business decisions based on unreliable data.
