Coursera 课程 “使用 R 进行数据分析的统计学” 是一门面向初学者的数据分析和统计学入门课程。本课程旨在教授学习者统计学基本概念，并通过 R 语言进行实践应用，即使没有编程经验也能轻松上手。 课程内容涵盖： * **描述性统计：** 学习均值、中位数、众数、四分位数、极差、四分位距和标准差等，并使用 R 的基础函数及 `psych` 包进行计算。 * **数据可视化：** 使用 R 的基础命令绘制直方图、箱线图和散点图等三种常用图表。 * **概率论基础：** 讲解排列组合等基本概念（仅理论）。 * **总体与抽样：** 介绍总体和抽样的基本概念（仅理论）。 * **概率分布：** 学习正态分布、二项分布和泊松分布，并使用 R 的基础函数及 `visualize` 包进行可视化。 * **假设检验：** 掌握单样本和双样本的 z 检验、t 检验、F 检验以及卡方检验。 * **方差分析 (ANOVA)：** 引导学习者逐步进行方差分析的计算，包括手动计算和使用 R 进行分析。 学员评价普遍认为该课程是理论与实践的完美结合，能够同时提升 R 语言能力和统计学水平。讲师 Sandeep 教授的讲解清晰、细致且富有条理，尤其适合初学者和非技术背景的学习者。课程帮助许多学员奠定了坚实的基础，为进一步学习更复杂的 R 和统计学知识做好了准备。 该课程提供 30 天无忧退款保证。
Perform simple or complex statistical calculations using R Programming! - You don't need to be a programmer for this:)Learn statistics, and apply these concepts in your workplace using R.The course will teach you the basic concepts related to Statistics and Data Analysis, and help you in applying these concepts. Various examples and data sets are used to explain the application.I will explain the basic theory first, and then I will show you how to use R to perform these calculations. The following areas of statistics are covered:Descriptive Statistics - Mean, Mode, Median, Quartile, Range, Inter Quartile Range, Standard Deviation. (Using base R function and the psych package)Data Visualization - 3 commonly used charts: Histogram, Box and Whisker Plot and Scatter Plot (using base R commands)Probability - Basic Concepts, Permutations, Combinations (Basic theory only)Population and Sampling - Basic concepts (theory only)Probability Distributions - Normal, Binomial and Poisson Distributions (Base R functions and the visualize package)Hypothesis Testing - One Sample and Two Samples - z Test, t-Test, F Test, Chi-Square TestANOVA - Perform Analysis of Variance (ANOVA) step by step doing the manual calculation and by using R.What are other students saying about this course?This course is a perfect mix of theory and practice. I highly recommend it for those who want to not only get good with R, but to also become proficient in statistics. (5 stars by Aaron Verive)You get both the "how" and "why" for both the statistics and R programming. I'm really happy with this course. (5 stars by Elizabeth Crook)Sandeep has such a clear approach, pedagogic and explains everything he does. Perfect for a novice like myself. (5 stars by Hashim Al-Haboobi)Very clear explanation. Coming from a non-technical background, it is immensely helpful that Prof. Sandeep Kumar is explaining all the minor details to prevent any scope for confusion. (5 stars by Ann Mary Biju)I had a limited background in R and statistics going into this course. I feel like this gave me the perfect foundation to progress to more complex topics in both of those areas. I'm very happy I took this course. (5 stars by Thach Phan)Dr. Kumar is a fantastic teacher who takes you step by step. Can't say enough about his approach. Detailed. Not only clear descriptions of statistics but you will learn many details that make R easier to use and understand. (5 stars by James Reynolds)This is a wonderful course, I do recommend it. The best Udemy course I took. (5 stars by Joao Alberto Arantes Do Amaral)The course exceeded my expectations and i would like to thank the instructor Mr Sandeep Kumar for creating such an amazing course. The best thing about this course is the Theory incorporated that helps you understand what you are going to code in R. I have really learnt a lot. If you a looking for the best course for R then look no further because this is the best there can be. (5 stars by Kipchumba Brian)What are you waiting for?This course comes with Udemy's 30 days money-back guarantee. If you are not satisfied with the course, get your money back.I hope to see you in the course.
