Harvard University stands first in the category of quality education and is undoubtedly recognized for sharing knowledge and learning opportunities. So, Harvard provides free courses relevant to Data Science for global learners. These courses are targeted towards an initiation audience but simultaneously can help an advanced audience in the sense that they can provide them with a comprehensive, fundamental base in the field of data science.
Data science incorporates statistical analysis, machine learning, data visualization tools, and programming techniques that assist in finding useful insights into the data. It is one of the most important disciplines in today's data-driven landscape and touches innumerable sectors. Free data science courses at Harvard are the best way to gain real skills and knowledge without spending any money.
This course "Data Science: R Basics" would lead students through the basics of R programming, which is one of the main instruments backing statistical analysis and data visualization. We will show you how you can use R in processes related to the manipulation of data, its analysis, and graphical representation.
In a nutshell, this eight-week-long course can be taken in roughly one or two hours during the week. This course will cover major topics: an introduction to R and RStudio, basic data types, and their operations. This course is going to teach how to do the basic structure of data in R: vectors, matrices, and data frames. The basic data manipulation will be done with dplyr, and for data visualization, it will be ggplot2. The course will be focused on theory and practice in visualization in R.
Visualization is a necessary part of the data science pipeline because it's how a practitioner communicates a discovery, or insight, realized from working with data. This is an eight-week course covered in one to two hours a week: principles of data visualization; how to create visualizations with ggplot2; understanding different plot types like scatter plots, bar charts and histograms and using them; and finally customizing and extending visualizations, including using interactive visualization tools.

The "Probability: Data Science" course will introduce students to the basis of probability theory, with agility in data science and a solid ground for understanding advanced topics in the field of statistical analysis. This is an eight-week commitment, requiring up to one to two hours of work every week. It shall cover topics in probability, conditional probability, Bayes' theorem, discrete and continuous random variables, their probability distributions, and joint and conditional distributions.
Application of probability to real-world problems. Basic methods of statistical inference, including estimation and hypothesis testing. The course builds, however, on the probabilistic foundations about making inferences with quantitative uncertainties at the beginning. Learn more.
"Data Science: Inference and Modeling" is about ways that allow statistical inference and modeling in detail.
These are some of the most important tools in the field of inference and single-based model evaluation. They will learn how to construct statistical models and how to test them. This is an eight-week course requiring, on average, one to two hours of weekly input. It will focus on techniques for statistical inference, hypothesis testing, confidence intervals, linear regression and correlation, model selection and validation, and an overview of Bayesian inference.

This course will relate students interactively to a range of productivity tools that will help them improve workflow efficiently towards the realization of successful data science projects: from version control and collaboration platforms to project management techniques. This is an eight-week-long course with an estimated hour starting from one to two hours per week.
Covered versions will include repo control with Git and Github, collaborative coding practices, data management and organization, reproducible research practices, and project management techniques for data science.
Besides the aforementioned, there are plenty of other free courses on the topic of Data Science and other subjects that relate to Data Science. All of these are offered as a product of HarvardX, an initiative through which learners across the globe can have a high-quality learning experience via a cyber platform. Learn more
