如何用excel制作数据分析?


严格意义上来讲,5000条数据称不上大数据,用excel是非常简单快捷的工具。给您提供简单的思路供参考。

1、确定分析思路。我们需要分析一个什么样的结果,简单介绍一下5W2H分析法,即何因(why),何事(what),何人(who),何时(when),何地(where),如何做(how),何价(how much),结合新生的数据情况,确认好要分析的目标。当然也有其他的分析方法,如PEST分析法,逻辑树分析法等。

2、数据处理。包括数据清洗和加工。比如日期格式,缺失值等。及时查漏补缺,确保数据的质量。这里要掌握一些基本的函数用法,比如:sum,average,dateif,vlookup等。

3、数据分析:主要用到的工具是数据透视表,他是一种交互式的报表,利用它,我们可以方便的调整分类汇总的方式,灵活的以多种不同方式展现数据特征。主要用的功能:数据排序,筛选,分类汇总等数据处理功能。

问题1、5000人中来自上海的学生有多少?

问题2、男生,女生的占比有多少?

问题3、重名人数有多少?

4、数据的展现。基本的图表有饼图,条形图,柱形图,折线图,散点图等,不同的图形用来暂时的重点也不一痒,占比建议用饼图,趋势建议用折线图等。
