感谢您选择“CDA 数据分析师”LevelⅠ学习系列丛书”之《从零进阶!数据分析的统计基础》 众所周知,数据分析的基础是统计学,没有概率论和数理统计的知识,数据分析尤如无根之草, 只能浮游在华丽的词藻上,数据分析师的职业发展之路也走不长远,因此掌握数据分析的统计学基础 知识是非常重要的。统计学作为一门学科,其内容之多,不是一本书能概括得了的,而为了使零基础 的读者,尽快进阶成一名具有统计基础的数据分析师,本书为此做出了积极的探索。取其精华,论其 重点,使读者能尽快地掌握一些数据分析师的统计学知识,这是本书的目的,也是学习本书的读 者所想要达到的终目标。掌握本书中的内容,您将在数据分析师这个职业之路上走得更远,更踏实。 本书按照数据分析的统计学基础知识来讲解,以三国武将数据为案例背景,由浅入深、由易 到难地向您展示统计学基础理论。由于三国时期的历史背景家喻户晓,读者可以不必费力地探究案例 的背景知识,让您能够将更多的精力放在学习核心的理论知识上,从而为今后的数据分析工作打下坚实的理论基础。
在 CDA(注册数据分析师)Level I 级教材付诸印刷之际,关于数据分析这个职业及其价值的报 道就有很多。比如,下面两条报道就充分体现了在大数据时代下,数据分析的价值。这在以前是从来 没有过的。
LinkedIn 的投票结果显示,‘统计分析和数据挖掘’是 2014 年的求职法宝。LinkedIn 对 全球超过 3.3 亿用户的工作经历和技能进行分析,公布 2014 年受雇主喜欢、炙手可热的 25 项技 能,其中位列榜首的是统计分析和数据挖掘。
麦肯锡公司的一份研究预测称,到 2018 年,在“具有深入分析能力的人才”方面,美国可能面临 着 14 万到 19 万人的缺口,而“可以利用大数据分析来做出有效决策的经理和分析师” 缺口则会达到150 万人。数据科学家将成为 2015 年热门的职业。
早在 2010 年 2 月,肯尼斯库克尔在《经济学人》上发表了一份关于管理信息的特别报告——《数 据,无所不在的数据》,文中写道:“世界上有着无法想象的巨量数字信息,并以极快的速度增长……
从经济界到科学界,从政府部门到艺术领域,很多地方都已感受到了这种巨量信息的影响。”2011 年, 麦肯锡发布了《大数据:下一个具有创新力、竞争力与生产力的前沿领域》,使人们在这篇文章里认识到了数据的力量。于是,一夜之间,面向数据分析市场的新产品、新技术、新服务、新业态正在不断 涌现。从个人、企业到国家层面,都把数据作为一种重要的战略资产,逐渐认识到了数据的价值,不 同程度地渗透到每个行业领域和部门,大大提升了企业的经营利润,推动了经济的发展。
这是一个用数据说话的时代,也是一个依靠数据竞争的时代。目前世界 500 强企业中,有 90%以 上都建立了数据分析部门。IBM、微软、Google 等知名公司都积极投资数据业务,建立数据部门,培养数据分析团队。各国政府和越来越多的企业意识到数据和信息已经成为企业的智力资产和资源,数据的分析和处理能力正在成为日益倚重的技术手段。 作为一个数学和统计学的强国,数据分析、数据挖掘和大数据价值挖掘行业在我国仍属于朝阳行业,数据分析人才仍然比较稀缺。各行各业在平常工作中积累的各种各样的数据分析问题仍然没有得 到及时有效地解决,有些问题,还是关乎本行业发展的至关重要的问题。数据积累越来越多,期待解 决分析的数据问题也越来越多,人们逐渐习惯使用数据作为决策的重要参考依据。据艾瑞的研究报告,未来与数据分析相关的就业岗位会在 1000 万人左右,而目前来说国内合格的数据分析师不足 5 万人, 建立一个科学有效的数据分析师培训体系迫在眉睫。
