How are sample size calculators vetted?

3

The calculator works in the reverse of the question. It can’t answer it.

4

Population size: 418
Sample size: 357

5

How does the sample size go from 132 → 357 → 381
When the population change goes from 200 → 5,000 → 50,000?
This doesn’t make any sense to me.
I would assume a much larger increase relative to population size.
