92/100Rarity: very rare
TechnicalRegister
The practice of repeatedly checking experiment results before the planned end and stopping as soon as significance appears, which inflates false positives.
Stop peeking at the dashboard; calling the test early just because p dipped below 0.05 is how we ship noise.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
