To decrease the standard error of their sampling distribution, researchers should increase the sample size. The standard error of the sample proportion is calculated as
. By increasing
, the denominator grows larger, which results in a smaller standard error, making their estimates more accurate and reliable.
It’s important to note that changing the sample proportion
does not directly affect the standard error in the same way. In fact, the term
reaches its maximum when
, so the key focus should always be on increasing that sample size to tighten up your estimates!
