Statistics (통계) is a branch of Mathematics dealing with the collection, analysis, interpretation, presentation, and organization of data. (https://en.wikipedia.org/wiki/Statistics)
통계학은 관찰 및 조사로 얻을 수 있는 데이터로부터, 응용 수학의 기법을 이용해 수치상의 성질, 규칙성 또는 불규칙성을 찾아낸다.
모집단(population)의 특징(모수, population parameter)은 직접 알기가 어렵다. 표본(sample)을 추출하여 모수를 추정하고자 함. 표본을 많이 추출하면 표본의 통계값은 정규분포를 한다. 그리고, 많이할수록 모수에 수렴한다. 이를 중심극한정리(Central limit theorem)라고 한다.
