How are sample size calculators vetted?

[joeyinvermont]

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

Population size: 418
Sample size: 357

[zackestabrook]

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.

hi
the population size in the first que can be 414 to 418, this result is showed by the calculator in this question

Answers:

1. Population Size: Between 414 and 418 - If Sample Size is 200.
2. If population size is 5 000 then Sample Size is 357.
