      Course Introduction
      강좌소개

      • 본 강의는 데이터 과학의 첫 단계인 데이터를 탐색하고 이해하는 과정을 배운다. EDA(Exploratory Data Analysis: 탐색적 데이터분석)라고도 불리는 이 과정은 데이터 분석에 사용될 데이터에 대한 이해도를 높이는 단계로서 수집된 데이터가 문제를 해결하는데 적합한지, 데이터에 특이사항이나 오류는 없는지, 어떤 분석 모델을 사용하는 것이 적합할지 등, 데이터의 특성에 대해 다각도로 살펴보고 고찰하는 과정이다. 이 과정은 향후 도출될 분석 모델의 질을 좌우하게 되므로 데이터 분석에 있어 매우 중요한 첫 단계라고 할 수 있다. 따라서 본 강의에서는 데이터를 다각도로 다루고 살펴보는 법과 다양한 시각화 기법을 학습한다. 본 강의는 이론과 실습을 병행하므로 학습자가 실제로 EDA를 하고 데이터 분석의 다음 단계로 나아가는데 필요한 입문 교육을 제공한다.

      학습목표

      • 이론과 실습을 통해 python환경에서 데이터를 다루고 다양한 시각화 기법을 데이터에 적용하고 그 결과를 해석하는 방법을 배운다. 이를 통해 데이터 분석을 위해 데이터를 다각도로 살펴볼 수 있게 된다.
