分析:
上述数据展示了不同商品之间的斯皮尔曼相关系数。斯皮尔曼相关系数用于衡量两个变量之间单调关系的强度和方向。系数取值范围为 -1 到 1,其中:
- 1 表示完全正相关,即一个变量增加,另一个变量也增加。* -1 表示完全负相关,即一个变量增加,另一个变量减少。* 0 表示没有单调相关关系。
例如,云南油麦菜和云南生菜的斯皮尔曼相关系数为 0.777389,表示它们之间存在较强的正相关关系。这意味着当云南油麦菜的销量增加时,云南生菜的销量也倾向于增加。
结论:
通过分析商品之间的斯皮尔曼相关系数,可以发现商品之间的潜在关联关系,这对于制定营销策略、优化商品组合等方面都具有重要意义。
注意: 相关性并不等同于因果关系。
