## Definition
|
||||
统计显著性检验,用于验证分析结论是否具有统计意义,而非随机偶然。
|
||||
|
||||
## Key Principles
|
||||
- P-value < 0.05:结果具有统计显著性
|
||||
- 95% 置信区间:标准置信水平
|
||||
- 样本量验证:确保样本量足够检测预期效应
|
||||
- 效应量(Effect Size):实际显著性而非仅统计显著性
|
||||
|
||||
## Application in Analytics
|
||||
- A/B 测试结果验证
|
||||
- 营销活动效果评估
|
||||
- 趋势识别确认
|
||||
- 预测模型准确性验证
