 Best Data Science Courses

1. Data Science Specialization by JHU @ Coursera

This course is one of the most popular & highly recommended course collections. JHU offered an excellent balance of breadth & depth in its curriculum. One thing incorporated in this course that’s generally missing from many data science courses is a whole part on statistics, which is the spine of data science.

Overall, this Data Science course is a perfect blend of theory & application using the R programming language. About qualifications, you must have some programming experience & knowledge & a good understanding of Algebra. Prior knowledge of Linear Algebra & Calculus isn’t compulsory but useful.

Price: Free or $49 per month for certificate & materials.

Provider: Johns Hopkins University.

2. Introduction to Data Science by Metis

One of the Best Data Science Courses — rated 4.9/5 on SwichUp & 4.8/5 on CourseReport — taught live by a famous data scientist from a top company. This one is a six-week data science course that includes almost everything in the data science process, & it’s among the only a few live online courses available.

Besides getting a certificate upon completion, you can obtain continuing education units since this course is recognized.

You can join the tutor with other students for two nights each week to learn data science like an online college course. Not only can you ask questions, but the tutor also devotes extra time for office hours to help students who might be struggling to understand.

Price: $750.

3. Data Science MicroMasters by UC San Diego @ edX

This course is advanced, graduate-level, and considered a real Master’s degree at chosen institutions. About this course, successfully finishing the courses & receiving a certificate will be seen as 35% of the Master of Science in Data Science degree from Rochester Institute of Technology.

Since these courses are driven toward potential Master’s students, so the required qualifications are higher than many other courses. Since the first one in this series doesn’t use much time teaching basic Python concepts, you should have the knowledge & experience of programming. Devoting time to a platform like Codecademy can prepare you to start with this one.

Price: Free or $1,260 for certificate & materials.

Provider: UC San Diego.

4. Applied Data Science with Python Specialization by UMich @ Coursera

The University of Michigan, which also introduced an online data science Master’s degree course, produced one of the top Online Data Science Courses focused on the practical side of data science. That means you will get a vivid introduction to frequently used data science Python libraries, such as matplotlib, pandas, scikit-learn, networkx & many more, and learn how to use them in the practical field.

This course doesn’t contain the statistics required for data science or the origins of different machine learning algorithms but offers an all-inclusive breakdown of ways to use & assess those algorithms in Python. This course would suit people with R programming language & learning statistical concepts.

Price: Free or $49 per month for certificate & materials.

Provider: University of Michigan.

5. Statistics and Data Science MicroMasters by MIT @ edX

The inclusion of possibility & statistics courses makes this course from MIT a very well-formed program to understand data intuitively. This MicroMaster’s from MIT devotes more time to statistical content than the UC San Diego MicroMaster’s cited earlier in the list.

Because of its advanced nature, you must have knowledge of single & multivariate calculus alongside Python programming. There isn’t any introduction to Python or R here like in some of the other courses mentioned here, so before starting the ML part, they suggest being familiar with Computer Science & Programming Using Python to know Python.
