前一段时间,我在研究LaTeX和数学时,恰好媒体在持续热炒“中专数学天才姜萍”。虽然我没有十足的证据证明造假,但是概率告诉我十有八九是假的。于是我做了这样一个表格,发到了小红书上。
今天测试了下阿里的通义千问qwen2:7B小模型,在我多次提示的情况下,它也很难正确计算假阳性的概率。
这让我想起,前一段时间在Slate Star CodeX上看到的一篇博客《Statistical Literacy Among Doctors Is Lower Than Chance》,说的是很多医生的统计学素养完全不及格。
文中提到42%的医生正确回答了下面这个判断题: “True or false: the p-value is the probability that the null hypothesis is correct“
第二道题是有5个选项的选择题,26%的医生回答正确: Ten out of every 1,000 women have breast cancer. Of these 10 women with breast cancer, 9 test positive. Of the 990 women without cancer, about 89 nevertheless test positive. A woman tests positive and wants to know whether she has breast cancer for sure, or at least what the chances are. What is the best answer?
两道都回答正确的医生只有12%
