If we repeatedly sample from a population samples of size n, and calculate the sample mean for each sample, the accumulation of these sample means would result in the an estimate of sample mean.

The median of a particular data set is 14.5. After checking the data, both the 2 smallest and 2 largest observed values are removed from the data set. Calculation of the median of the new data set yields a number of 14.5

The p-value from a statistical test of significance gives the smallest probability of the null hypothesis being true.
