1. The Instructors Reputation

The course is created by three instructors and let’s start with Jeff Leek who is an assistant professor at John Hopkins University in biostatistics specialization and has a Ph.D. in this field.

Another instructor called Roger D. Peng and also has a Ph.D. in statistics from California university and works as a professor at John Hopkins University as well.

The last instructor his name Brian Caffo and he is as well a professor at John Hopkins University and a Ph.D. holder from the University of Florida is the biostatistics specialization. 

2. The Specialization Content

This data science specialization focuses mainly on using the R programming language to do analyze and visualize the data as well as creating machine learning models. So let’s start exploring the content of this course: 

2.1. The Data Scientist’s Toolbox

Since you are new to the data science field you will get an introduction to this industry as well as some tools and platforms that will help you master data science.


2.2. R Programming

The second one focuses on programming using the R Programming language since it is the main one to do analysis and visualization in this course as well as installing the environment and packages for statistical programming.  Btw, if you want to master the R language, you can also check out my list of best R programming courses which include the best courses from Udemy, Pluralsight, and Coursera to learn R programming. 

2.3. Getting and Cleaning Data

Before you can do your job as a data scientist you need first to obtain and collect the data so this course will introduce you to the various ways on how to get data from databases as well as the web and more.

This course will introduce you to statistics and inference statistics which is the process of drawing the conclusion of a population as well as some theories such as Bayesian and likelihood.

2.7. Regression Models

This course is toward statistical analysis as well as regression models such as linear and regression models so it is an introduction to machine learning and regression analysis. 

2.8. Practical Machine Learning

Here where it comes to the fun part where you will apply machine learning algorithms to your data as well as prediction functions and some ML concepts such as training overfitting and more. 

2.9. Developing Data Products

This course is all about creating data products using the R language as well as some packages such as shiny and leaflets and you will learn some visualization using the Plotly library. 

2.10. Data Science Capstone

In the last course, you will do a capstone project where you will develop a data product using what you have learned in the past courses as well as analyze your data and make predictions, and more. 

3. The People Review

The specialization gets 4.5 stars out of 5 from around 78k who submitted their rating which seems pretty good and means the content itself is also good as well as the videos and quizzes.

It also has more than 350k enrollment and forgets to mention that the course is available in many languages such as Chines and Arabic as well as Spanish Russian and more and the statistics show that 43% of the learners has started a new career in data science and around 19% has got promotion after completing this specialization.
