Explanation / Answer

Sampling error gives the difference between sample mean and population mean.

If treatment works sample mean may be different from popualiton mean. Likewsie if the IV truly does affect the DV sample mean may differ the population mean.

Sampling distribution in the log run approaches to population mean. So it is not the reason your sample mean different from your population mean.
