What the data shows
"a few"it's 3. it's always 3- "A few" is always 3: at a dinner, at a stadium, in an inbox, on the floor, in years.
- "Several" barely moves: 3 at dinner, at the stadium and in the inbox; 4 for rice and years.
- "Many" scales strongly: 6 to 7 years, 11 to 15 emails, 16 to 25 dinner guests, 101 to 250 grains of rice, 251 to 500 people at a stadium.
What it means, and what it doesn't
Jev treats "a few" and "several" as fixed small numbers, and "many" as relative to the situation. A person would likely scale all three to some degree, so Jev's "a few people at the stadium" is likely smaller than a person's. For "many", it reads the situation well.
Without human answers this shows Jev's pattern, not a gap with people, and 15 answers is a small grid. For the words without any setting, see "How many is 'a few'?".
