Neutral         Shorter than I expected         6
Unsatisfied     Did not receive a response      1
Very satisfied  Much shorter than I expected    10
Very unsatisfied    About what I expected       1
Very satisfied  Shorter than I expected         10
Very satisfied  Shorter than I expected         8

回答以下问题的最佳方法是什么：如果响应者回答 Q2 时“比预期短得多”，那么 Q3 的概率是 10。

我正在寻找明确的答案或如何指导我将来可以学习如何做到这一点。我想在 excel 或 pandas 中完成此操作。

我可以使用逻辑回归并为 Q2 分配一个虚拟变量吗？我能否以某种方式创建一个相关矩阵来查看 Q2 的响应与 Q3 的相关性如何？

Answer 1

您可以使用公式计算：

=(COUNTIFS($B$2:$B$37,"Much shorter than I expected",$C$2:$C$37,10)/COUNTIF($B42:$B$37,"Much shorter than I expected"))*100

我们给它B2:B37 的范围来检查答案“比我预期的要短得多”

当我们找到它时，我们会检查他们是否给 Q3 打了 10。

然后我们将正确的数字与他们回答“比我预期的要短得多”的总次数相乘，乘以 100 并四舍五入到小数点后 2 位。

公式示例：

你也可以修改这个公式来接受不同的参数：

=(COUNTIFS($B$2:$B$37,E2,$C$2:$C$37,F2)/COUNTIF($B$2:$B$37,E2))*100

如果您只是想知道计算概率的数学方法，请按以下步骤操作：

1. 定义您的事件和结果。
2. 将事件数除以可能结果数。
3. 将答案乘以 100 得到百分比。
4. 使用百分比作为答案。
