데이터 분석의 신비 해제: 시작하기 위한 초보자 가이드

데이터 분석이란 무엇이고 어떻게 시작할 수 있나요?

데이터 분석이란? 의미 있는 통찰력을 발견하기 위해 데이터를 검사, 정리, 변환 및 해석하는 프로세스입니다.

데이터 분석의 중요성: 데이터 분석은 기업이 정보에 입각한 결정을 내리고, 기회를 파악하고, 문제를 감지하는 데 도움이 됩니다.

데이터 수집: 관련 데이터를 수집하는 것으로 시작하세요. 이는 설문 조사, 센서, 데이터베이스 또는 웹 스크래핑을 통해 수행될 수 있습니다.

데이터 정리: 원시 데이터는 종종 지저분하고 불완전합니다. 정리에는 중복 제거, 누락된 값 처리 및 오류 수정이 포함됩니다.
