About the 数据分析基础 certification
一项基础级认证，从零开始构建清晰、可用的数据分析心智模型。你将学习数据分析究竟是什么，以及分析生命周期如何从问题出发，经由数据与洞察，最终到达决策；结构化、半结构化与非结构化数据的区别；如何按数据类型和测量尺度（名义、序数、区间、比率）对变量进行分类，以及为何尺度决定了哪些统计量有效；描述性统计核心——均值、中位数与众数，方差、标准差与百分位数所捕捉的离散程度，以及各指标的适用情形；数据的来源与采集方式；数据清洗与质量管理——处理缺失值、异常值与重复数据；四类分析（描述性、诊断性、预测性、规范性）及各自回答的问题；为信息选择合适图表的基本原则；电子表格与数据库的权衡取舍；SQL数据查询简介；相关性与因果关系的关键区别；KPI与指标如何将目标转化为可衡量的信号；以及数据伦理与隐私要点。该认证与工具无关——每个概念均可清晰映射至电子表格、SQL、Python或R以及现代BI工具——因此所学知识适用于任何后续方向。这是进入更专业的数据与分析认证的自然第一步。
