Examples of The Best Data Science Courses Online
Here are examples of what the best data analytics courses online can do for you, using Python, R, SQL, and AI as examples.
Python
Python is one of the most popular and versatile languages for data science and programming. Therefore, it’s no surprise that many of the best data science courses online revolve around Python.
If you’re just starting out learning Python, there are plenty of analytics courses online where you can dip your toes in the water. For example, edX and the University of Michigan’s 7-week course entitled “Programming for Everybody (Getting Started with Python)” is one of the best online data science courses for beginners.
To include Python in your certifications for data analytics, check out courses like Edureka’s instructor-led live “Python Certification Training for Data Science” class or Springboard’s live one-on-one “Data Science Bootcamp” online. These certifications for data analytics give you official Python accreditation and prepare you for a job in data science or related professions in months.
R
While Python is an all-purpose language, R is the most important language for doing statistical analysis and data visualization. Therefore, it’s worth learning both R and Python as part of your big data training online or as part of an online data analyst certification.
DataCamp’s “Data Analyst with R” and “Data Scientist with R” are both strong candidates for best data science certification online. Other providers offer R learning as part of broader data science online courses. For example, Udacity’s “Programming for Data Science with R” incorporates training in R, SQL, command line, and git.
SQL
SQL is the standard language for relational database management systems and an essential skill for jobs involving data analysis, web development and programming. According to a recent survey of job posts mentioning the word ‘data’ on Indeed.com, SQL is mentioned in 36% of jobs. Therefore, SQL is an important component of many of the best courses for data science online.
The best SQL course for you depends how much you need to learn and whether you want to receive an online data analyst certification at the end of your studies. Many of the best data science courses online platforms offer SQL beginners courses focusing on Oracle SQL or Microsoft SQL Server. Some certifications for data analytics incorporate SQL into the coursework, such as “MySQL for Data Analytics and Business Intelligence” on Udemy.
Artificial Intelligence
Artificial intelligence, machine learning and deep learning are at the cutting-edge of data science. If you’ve completed your initial data science online training and are looking to take your career to the next level with a certificate in big data analytics, then AI is where you want to be.
Udacity’s “Artificial Intelligence Nanodegree” is one of the best data science online courses for anyone looking to develop their AI skills. Prerequisites for this course include algebra, calculus, statistics, and Python. “Data Science Specialization” from Coursera and Johns Hopkins University, a candidate for best data science certification online, includes extensive coursework on using AI and machine learning in data analytics.
Online Courses: Your Launching Pad for a Career in Data Science
Platforms that let you learn data science online are a great equalizer. No matter where in the world you live and what your previous skillset, you can pick up virtually any big data online course.
