This course is the third course in a 3-part specialization entitled "Statistics and Applied Data Analysis." The course is meant for those familiar with statistics but unfamiliar with the programming language R.
The purpose of this course is to teach learners how to use the popular open-source (and thus, free) integrated development environment RStudio to perform basic and complex statistical calculations.
After an introduction to basic calculations, vector, matrices, data frames, and how to import data from common file types (.xlsx, .csv, .txt), learners are taught how to solve probability and counting problems in R, followed by discrete and continuous probability distribution calculations, one-sample hypothesis tests, and two-sample hypothesis tests (comparisons). Finally, participants will learn how to create regression models in R and perform analysis of variance (ANOVA).
One of the most beneficial aspect of the course are the programming assignments, which are completed online in the R programming language in Jupyter notebooks.
Welcome to "Statistics and Data Analysis with R"! In this week, you will be introduced to R and RStudio and will learn how to install and navigate RStudio. You will then learn how to perform basic calculations, use script files, create and work with vectors and matrices, and install and load add-on packages. Finally, you will learn all about data frames and tibbles, how to import data from external files (.xlsx, .csv, and .txt files), and how to work with built-in and user-defined functions. When you are ready, you must pass the Week 1 Graded Quiz in order to access the Week 2 Starter Files and Cheat Sheet. You will need access to these items in order to complete Module 2. You must also pass Assignment 1, which counts towards the final grade in the course.

第 2 单元•小时 后完成
单元详情
In Week 2, you'll learn how to calculate common descriptive statistics in R, how to calculate conditional statistics, and how to present data in a graphical manner (scatter plots, column plots, and pie plots). You'll also learn how to create boxplots and probability plots in R and how to analyze the normality of the data using the Anderson-Darling statistic. Week 2 has 9 screencasts with many in-video questions to test your understanding of the material and help you learn. The week ends with a hands-on Assignment 2, which you will complete in a Jupyter notebook in the programming language R and that counts towards your final grade in the course. When you are ready, you must pass the Week 2 Graded Quiz in order to access the Week 3 Starter Files and Cheat Sheet. You will need access to these items in order to complete Module 3.
Best of luck to you this week! As always, if you have questions or issues, please initiate a discussion thread and either myself or someone else will chime in with some help.

In Week 4, you'll learn all about how to calculate one-sample statistics in R. You will begin the week by learning how to calculate confidence and prediction intervals on the mean, variance, and binomial proportion. Then, you will learn how to perform hypothesis tests on the mean, variance, and a binomial proportion. You will also learn how to calculate the power and probability of a type II error in R, which is related to sample size considerations, which you will also explore. Week 4 has 10 screencasts with many in-video questions to test your understanding of the material and help you learn. I encourage you to download and make use of the Week 4 Cheat Sheet (for those who purchase a Course Certificate) as this will help distill the challenging concepts and R functions that are found in this week's material. Week 4 concludes with Assignment 4, which you will complete in the R programming language in a Jupyter notebook and that counts towards your final grade in the course. When you are ready, you must pass the Week 4 Graded Quiz in order to access the Week 5 Starter Files and Cheat Sheet. You will need access to these items in order to complete Module 5.

Regression and ANOVA
第 6 单元•小时 后完成
单元详情
In Week 6, you'll learn all about creating simple linear, polynomial, and multilinear regression models, which basically are mathematical relationships between input variables (regressor variables) and an output variable (response). You will learn how to calculate confidence intervals on and perform hypothesis tests on model parameters and you will learn how to select the best possible regression model from several candidate models using backward elimination. Finally, you will learn how to perform analysis of variance (ANOVA) when you have more than two groups to compare. Week 6 has 9 screencasts with many in-video questions to test your understanding of the material and help you learn. The week concludes with Assignment 6. When you are ready, you must pass Quiz 6 in order to continue in the course. You will also want to pay close attention to the Week 6 Cheat Sheet (available to learners who purchase a Course Certificate) as this will serve as a great reference for Assignment 6 and Quiz 6.

When will I have access to the lectures and assignments?
To access the course materials, assignments and to earn a Certificate, you will need to purchase the Certificate experience when you enroll in a course. You can try a Free Trial instead, or apply for Financial Aid. The course may offer 'Full Course, No Certificate' instead. This option lets you see all course materials, submit required assessments, and get a final grade. This also means that you will not be able to purchase a Certificate experience.
What will I get if I subscribe to this Specialization?
When you enroll in the course, you get access to all of the courses in the Specialization, and you earn a certificate when you complete the work. Your electronic Certificate will be added to your Accomplishments page - from there, you can print your Certificate or add it to your LinkedIn profile.
Is financial aid available?
Yes. In select learning programs, you can apply for financial aid or a scholarship if you can’t afford the enrollment fee. If fin aid or scholarship is available for your learning program selection, you’ll find a link to apply on the description page.
