Also, in the analysis are data analysis methods such as the mean, the median, the mode, standard deviation, kurtosis, and skewness.

The paper "What Are the Contributions of Sampling Distribution Models" is a worthy example of an assignment on statistics. Samples are used in statistics to prepare distribution models like histograms and then extrapolating or inferring the results into the entire set of population. For a distribution to be close to normal representation, then a larger sample size is deemed necessary.
