18 Best Online Courses on Data Science and Machine Learning
It is one of the most enrolled in and highly rated online courses in data science across the globe. JHU did an incredible job with the balance of breadth and depth in the curriculum. One thing that’s included in this series that’s usually missing from many data science courses is a complete section on statistics, which is the backbone of data science.
The Data Science specialization is an ideal mix of theory and application using the R programming language. As far as prerequisites go, you should have some programming experience (doesn’t have to be R) and you have a good understanding of Algebra. Previous knowledge of Linear Algebra and/or Calculus isn’t necessary, but it is helpful.
For learners with financial constraints, Coursera does waive the course fee as well.
- The Data Scientist’s Toolbox
- R Programming
- Getting and Cleaning Data
- Exploratory Data Analysis
- Reproducible Research
- Statistical Inference
- Regression Models
- Practical Machine Learning
- Developing Data Products
- Data Science Capstone
This is appropriate for someone that already knows R and/or is learning the statistical concepts elsewhere. One of the best courses in the market for the folks who want to learn python for data science.
Learners will get introduced to commonly used tools in data science like Python libraries, like matplotlib, pandas, nltk, scikit-learn, and networkx, and also learn how to use them on real data.
- Introduction to Data Science in Python
- Applied Plotting, Charting & Data Representation in Python
- Applied Machine Learning in Python
- Applied Text Mining in Python
- Applied Social Network Analysis in Python
MicroMasters from edX are advanced, graduate-level courses that carry real credits you can apply to a select number of graduate degrees. The inclusion of probability and statistics courses makes this series from MIT a very well-rounded curriculum for being able to understand data intuitively. It’s a great data science certification.
You will begin from the very basics of probability and statistics before moving on to data analysis techniques and machine learning algorithms.
Due to its advanced nature, you should have experience with single and multivariate calculus, as well as Python programming. There isn’t any introduction to Python or R like in some of the other courses in this list, so before starting the ML portion, they recommend taking Introduction to Computer Science and Programming Using Python to get familiar with Python.
A very reasonably priced course for the value. It’s a comprehensive course, developed by Jose Portilla (Santa Clara University) and Pierian Data International. It has large chunks of machine learning content but covers the whole data science process. It’s more of a very detailed introduction to Python. Probably, the best course for python training and for introduction to machine learning with python.
The instructor does an outstanding job explaining the Python, visualization, and statistical learning concepts needed for all data science projects. A huge benefit to this course over other Udemy courses are the assignments. Throughout the course you’ll break away and work on Jupyter notebook workbooks to solidify your understanding, then the instructor follows up with a solutions video to thoroughly explain each part.
You will learn how to use Python to analyze data (big data analytics), create beautiful visualizations (data visualization) and use powerful machine learning algorithms. You will specifically get to learn how to use NumPy, Seaborn, Matplotlib, Pandas, Scikit-Learn, Machine Learning, Plotly, Tensorflow and more.
- Python Crash Course
- Python for Data Analysis – Numpy, Pandas
- Python for Data Visualization – Matplotlib, Seaborn, Plotly, Cufflinks, Geographic plotting
- Data Capstone Project
- Machine learning – Regression, kNN, Trees and Forests, SVM, K-Means, PCA
- Recommender Systems
- Natural Language Processing
- Big Data and Spark
- Neural Nets and Deep Learning
If you have decided to pursue a career in Data Science or machine learning then this is a fairly good place to begin. It has got a very well designed content and all the topics are covered elaborately.
This certification consists of a series of 9 courses that help you to acquire skills that are required to work on the projects available in the industry. The lectures cover a wide range of topics including data visualization, analysis, libraries, and open-source tools.

This professional program by Microsoft consists of 9 courses in addition to a project and will take about 16 – 32 hours per course. It is a 10-course program and you can also choose individual courses if you want.
Subjects covered include probability and statistics, data exploration, visualization, and an introduction to machine learning, using the Microsoft Azure framework. Although all of the course material is free, students can pay ($90 in this case) for an official certificate on completion.
You will learn about using Microsoft Excel to explore data, using Transact-SQL to query a relational database, creating data models using Excel or Power BI, applying statistical methods to data and using R or Python to explore and transform data Follow a data science methodology.
This course from the University of Washington is about scalable data management. It covers data science topics including scalable SQL and NoSQL data management solutions, data mining algorithms, and practical statistical and machine learning concepts. It’ll also deal with privacy, ethics, and governance concerning this field.
In the final Capstone Project, developed in partnership with the digital internship platform Coursolve, you’ll apply your new skills to a real-world data science project.
Here is another pretty solid data science online course. In this Specialization, you will learn to analyze and visualize data in R and create reproducible data analysis reports, demonstrate a conceptual understanding of the unified nature of statistical inference.
You will perform frequentist and Bayesian statistical inference and modeling to understand natural phenomena and make data-based decisions, communicate statistical results correctly, effectively, and in context without relying on statistical jargon, critique data-based claims and evaluated data-based decisions.
Additionally, you will also learn data wrangling and data visualization with R packages for data analysis.
This 5-week accelerated online specialization provides participants a hands-on introduction to designing and building data processing systems on Google Cloud Platform. Participants will learn how to design data processing systems, build end-to-end data pipelines, analyze data and carry out machine learning.
