Sample size
Definition
Sample size is the number of observations that sit behind a reported rate.
Why it matters
AI answers vary between runs, so small samples swing widely. Showing the sample size beside every rate tells the reader how much weight it can bear.
Example
"30 percent, from 40 observations" is far more informative than "30 percent".
