[2025-10-02T01:22:15.643429] [PI reasoning] **Explaining normal distribution**

I need to clarify how normal distribution works. The fraction of data between the mean and +1 standard deviation is 34%, which is derived from the overall 68% of data within ±1 standard deviation. Since the median in a normal distribution is the same as the mean, the answer to a question about “between the median and median plus one standard deviation” is also 0.34. I’ll make sure to include a citation for accuracy, possibly referencing Altman 1991.

[2025-10-02T01:22:38.240873] [PI reasoning] **Searching for articles on distributions**

I’m finding it tough to search because "normal distribution" has a lot of competing content. I think referencing a well-known article might help, especially one tied to PMID 11103005, which discusses the 95% area between -1.96. Even if I can't get the exact figure, I can still explain that 68% of the area lies within one standard deviation from the mean, meaning 34% is above the mean up to +1 SD. Let's finalize the answer!
