课程名称：数据科学的基础统计学与数据挖掘 课程概述：数据科学是一个不断发展的领域，正迅速受到重视。它结合了统计学、计算机科学，以及机器学习、数据库和可视化等领域的技术和理论。本视频课程提供了逐步的数据分析入门和统计学基础。第一章重点介绍数据分析的步骤以及针对不同数据类型的相关汇总统计。第二章继续关注单个变量的汇总，并探讨用户需要汇总变量的一些原因。该章节还展示了数种程序，例如如何运行和解读频数，以及如何创建各种图表。第三章引入了推断统计、概率及假设检验的概念。后续章节则教授如何执行和解读基本统计分析的结果（如卡方检验、独立及配对样本t检验、一元方差分析、事后检验和双变量相关）及图形展示（如分组条形图、误差条图和散点图）。您将学习何时使用不同的统计技术、如何设置不同的分析，以及如何解读结果。 作者简介：耶稣·萨尔塞多（Jesus Salcedo）拥有福特汉姆大学的心理测量学博士学位，担任独立统计顾问，并在过去20多年里使用SPSS产品。他曾担任SPSS课程团队负责人和高级教育专家，撰写了许多SPSS培训课程，并培训了数千名用户。
Data science is an ever-evolving field, with exponentially growing popularity. Data science includes techniques and theories extracted from the fields of statistics, computer science, and most importantly machine learning, databases, and visualization. This video course consists of step-by-step introductions to analyze data and the basics of statistics. The first chapter focuses on the steps to analyze data and which summary statistics are relevant given the type of data you are summarizing. The second chapter continues by focusing on summarizing individual variables and specifically some of the reasons users need to summarize variables. This chapter also illustrates several procedures, such as how to run and interpret frequencies and how to create various graphs. The third chapter introduces the idea of inferential statistics, probability, and hypothesis testing. The rest of the chapters show you how to perform and interpret the results of basic statistical analyses (chi-square, independent and paired sample t-tests, one-way ANOVA, post-hoc tests, and bivariate correlations) and graphical displays (clustered bar charts, error bar charts, and scatterplots). You will also learn when to use different statistical techniques, how to set up different analyses, and how to interpret the results.
