Overview of Harvard’s Free Data Science Courses

Harvard University provides a range of free data science courses that cater to learners of all levels, from beginners to advanced practitioners. Let’s explore five standout courses that can equip you with the necessary knowledge and skills to excel in the field of data science.

Course 1: Introduction to Data Science

If youā€™d like to learn R, Harvard offers an introductory R course created specifically for data science learners, calledĀ Data Science: R Basics. This program will take you through R concepts like variables, data types, vector arithmetic, and indexing. You will also learn to wrangle data with libraries like dplyr and create plots to visualize data.

If you prefer Python, you can choose to take CS50ā€™s Introduction to Programming with Python offered for free by Harvard. In this course, you will learn concepts like functions, arguments, variables, data types, conditional statements, loops, objects, methods, and more.

Course 2: Visualization

Visualization is one of the most powerful techniques with which you can translate your findings in data to another person. WithĀ Harvardā€™s Data VisualizationĀ program, you will learn to build visualizations using the ggplot2 library in R, along with the principles of communicating data-driven insights.

Course 3: Statistics

Statistical inference and modeling are indispensable for analyzing data affected by chance, and thus essential for data scientists. In this course, you will learn these key concepts through a motivating case study on election forecasting.

Course 4: Machine Learning

Perhaps the most popular data science methodologies come from machine learning. You will learn about training data, and how to use a set of data to discover potentially predictive relationships. As you build the movie recommendation system, you will learn how to train algorithms using training data so you can predict the outcome for future datasets. You will also learn about overtraining and techniques to avoid it such as cross-validation. All of these skills are fundamental to machine learning.
