A comprehensive introduction to descriptive statistics, focusing on how to organize and interpret numerical datasets. It highlights central tendency through the mean and median, explaining when each measure best represents a typical value. The text also examines measures of dispersion, specifically variance and standard deviation, to illustrate how data points are spread around an average.
