Accepted Answer

When estimating the mean we use the arithmetic mean which is not a robust measure. Population shape shows the frequency of values that can be obtained by sampling the entire population. For small samples we can't be sure it represents the population in a good way. When the sample size increases we can be more and more sure that our sample represents the population.
