Neutral         Shorter than I expected         8
Very satisfied  Shorter than I expected         6
Satisfied       About what I expected           8
Very satisfied  Much shorter than I expected    10

Satisfied       Shorter than I expected         9
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：如果响应者回答Q2并且＃34;比预期的短得多＆＃34;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会这样做。我想在excel或pandas中实现这一目标。

我可以使用Logistic回归并为Q2分配虚拟变量吗？我可以以某种方式创建一个相关矩阵，看看Q2的响应与Q3的相关性如何？

Answer 1

您可以使用以下公式计算：

=(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

我们给它范围B2:B37以检查答案＆＃34;比我预期的短得多＆＃34;

当我们找到它时，我们检查他们是否给了Q3的10。

然后我们将它所在的数字乘以它们回答的总次数＃34;比我预期的短得多＆＃34;，乘以100并舍入到2位小数。

公式示例：

您还可以修改此公式以接受不同的参数：

=(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，请按以下步骤操作：

定义您的活动和结果。
将事件数除以可能的结果数。
将答案乘以100，使其成为百分比。
使用百分比作为答案。
