The mean of a sampling distribution can be considered an unbiased estimate of $\mu$ when
There is no major skewness or outliers.
Variability is uncertain at first but gets smaller as $n$ increases.
The sample mean and population mean $\mu$ are equal.
Samples are conducted in such a way that the population is well represented.
Its expected value changes as the sample size $n$ increases.
