The study of statistics is the failed attempt to study sample paths in a stochastic dynamic system.
Systems that is are so complex or chaotic that each sample path manifest very rich or seemingly random behavior.
Unable to figure out why, statisticians resort to the study of its average, means, and variances by combining may sample paths and study aggregated behavior.
However, this usually won't solve any problem, because the real mechanics behind of an observed event is usually hidden in the causal relationship within each sample path.
That's why medical science is progressing so slowly and unpredictably.
