An increase in the level of confidence leads to a larger minimum sample size requirement. This is because higher confidence levels correspond to wider confidence intervals, meaning we need more data to ensure that our estimate falls within this range. Think of it like this: the more certain you want to be about your findings, the more data you’ll need to back it up!
On the flip side, increasing the error tolerance actually decreases the minimum sample size requirement. When you’re okay with a larger margin of error, you can achieve your objective with fewer samples. It’s like saying, “I don’t need to hit the bullseye every time; a close shot is good enough!” Hence, you can relax the strict need for precision and save on the number of surveys or experiments required.
