课程简介

课程名称:使用R编程的单变量分析 课程概述:本课程旨在教授如何使用R和R Studio进行单变量数据分析。学习者将首先安装R和R Studio,并利用R Studio探索数据,使用表格和标题呈现结果。 课程内容包括: - 使用R Studio计算数值数据的摘要统计量,如均值、中位数和分位数,以了解数据分布。 - 计算数值数据的扩散性统计量,包括极差、方差、标准差和四分位距,并解读这些扩散性测量,以识别风险。 - 将摘要统计结果以表格形式呈现,并配以标题。 - 利用R Studio绘制数值数据的直方图,学习如何通过直方图解读数据分布。 - 绘制数值数据的箱线图,理解箱线图以推断数据分布及不同分位数。 - 对分类数据计算摘要统计量(计数、比例和百分比),并使用R Studio绘制条形图和树形图。 - 利用条形图和树形图识别最常见和最少见的类别。 - 学习如何自定义图表,制作同一数据的不同版本图表。 - 学会将制作的图表导出为PDF或图像,或复制到剪贴板,以便在报告中使用。 通过本课程,参与者将掌握使用R进行单变量分析的基本技能,能够高效呈现和解释各种数据分析结果。
