descriptive statistics
Descriptive statistics are a way to get a sense of the "shape" of data which is already quantitative. On this project, we take the term to mean the five-number summary { sample minimum, first quartile, median, third quartile, sample maximum }, plus the average (arithmetic mean) and standard deviation.
