- A five-sigma result is considered the gold standard for significance, corresponding to about a one-in-a-million chance that the findings are just a result of random variations.
- In particle physics, five-sigma is the accepted level of significance required to declare a discovery, corresponding to a probability of 0.00002%.

Standard deviation - Wikipedia
A large standard deviation indicates that the data points can spread far from the mean and a small standard deviation indicates that they are clustered closely around the mean.
For example, each of the three populations {0, 0, 14, 14}, {0, 6, 8, 14} and {6, 6, 8, 8} has a mean of 7. Their standard deviations are 7, 5, and 1, respectively. …Wikipedia · Text under CC-BY-SA license55 Gen Alpha Slang Words (With Meanings) - Parade
