This guide is all about data science courses, including where to find courses, what to expect, and how taking a course can help boost a career.
Regularly, you’ll find a data scientist juggling massive chunks of structured and unstructured data to analyze, process, and interpret the results to help companies craft actionable plans. Such a complex role requires a powerful combination of statistics, computer science, and mathematics.
Advanced social science and technology knowledge helps data scientists hunt for trends, manage complex data, and help businesses discover valuable solutions to complicated challenges.
Sure, the role of data scientists makes them indispensable for companies across the globe. The Bureau of Labour and Statistics (BLS) even predicts a 23 percent employment rise for computer information and research scientists between 2022 to 2032. But when a college degree might not be an option, what other alternatives can you take to kickstart your career in data science?
A data science course is the answer.
Data Science Courses Overview
Data science courses help learners master the skills needed in the profession within a comparatively shorter period. These courses help you navigate the entire data science process through open-source programming tools and libraries.
During the course, your instructors will cover elements like the most recent machine learning algorithms alongside introducing hands-on projects and assignments to help you gain practical knowledge of the field.
Data science courses are a flexible alternative to college degrees – they are either available every month or come with on-demand access. General data science courses typically cover a few or all the core skills associated with the profession. These include:
A significant part of a data scientist’s role involves creating graphs and charts using:
Through programming languages, data scientists navigate through oceans of data using:
When you incorporate deep learning and machine learning into your work, you consistently improve the data quality. Machine learning helps data scientists predict the results of future datasets.
Aside from general courses, some learners might be hunting for specific skills within data science like SQL and deep learning, among many other topics. Specialized data science courses can help people acquire or upgrade their skills within the subject.
How much do online data science courses cost? The answer is, “it depends.” Many courses are available for free if you choose to audit the course instead of opting for the certification. Courses can also range from $49 to over $1300 or more based on your needs and what the course providers offer.
Some courses offer a free trial, while others can open up routes to valuable certifications or MicroDegrees. If you’re looking at a master’s program from a reputable university, you can expect to pay a tuition fee ranging from $9,900 to $42,000. Bootcamps are another alternative with a price tag floating anywhere between $8,940 to $16,000.
The timeline of a data science course spreads across 6 to 9 months—considering you dedicate 6 to 7 hours each day to stay on track with the curriculum.
