How Do You Choose a Data Science Course?
Choosing the right data science course is a matter of personal fit. Before doing your research, think about what you’re interested in learning, what you want to achieve, and how much time and money you are able to invest in your education. There are many subtopics in data science and courses designed for learners of all abilities. Having a clear picture of your needs before doing the research will help you pinpoint the right course for you. Here are some considerations to make:
The type of data science course you choose depends on your career objectives and current skill level. If you have some experience with general-purpose programming, statistics, or data analysis, short courses are a great way to improve your skills in an area of weakness. Most courses require students to be familiar with coding in Python and have comfort with basic statistical techniques. On the other hand, students who are trying to switch careers, especially those with a non-technical background, will benefit from a more hands-on, long-term program like Springboard’s, which provides support services such as 1:1 mentorship, career coaching, access to the Springboard community, and the opportunity to create portfolio-ready projects to show prospective employers.
Course content and duration are other key considerations. Some courses are more advanced than others. Introductory data science courses will teach you the real-world applications of data science and key analytical techniques. These courses are a great way to gauge your interest in pursuing a data science career or lay the theoretical foundation for more advanced learning. Be honest with yourself about your current skill level.
Next, consider the quality of the course content. Does it cover the entire data science process, from data cleaning to analysis and visualization? Does it use popular open-source programming tools and libraries? Is there a good combination of theory and application? Also, consider how many hours of content the course offers.
If you have some programming knowledge, are currently learning data science, or already working as a data professional, choose a course that focuses on specific skills in data science, such as how to use Tableau for advanced data visualizations, how to use machine learning to build recommendation engines or artificial intelligence. Ideally, you want to choose a course focused on the programming language of your choice so you can implement your new knowledge immediately.
Determine your budget for pursuing further education. Does your employer provide a learning & development stipend or tuition reimbursement? Verify what types of programs or institutions are approved by your employer. If you’re paying for the course out of pocket, consider whether you can afford to pay upfront. Using a monthly payment plan may be more expensive in the long run, especially if unexpected circumstances keep you from completing the course on time.
Some MOOCs (Massive Open Online Courses) can be audited for free, but you may wish to earn a certificate to show prospective employers your skills.
Also, verify whether the course provides limited or lifetime access to learning materials. The downside of free courses is you generally lose access to course material within days or weeks of completing the program. Consider your needs and career objectives when determining which course will provide the best value for money. If you are attempting to switch careers, you may benefit from enrolling in a data science bootcamp rather than pursuing self-directed learning or taking individual courses in a piecemeal fashion. Bootcamps offer mentorship, career coaching, and a structured, comprehensive curriculum.
Always check the reviews before enrolling in a course. A high number of positive reviews indicates students can vouch for the success of a program. Pay close attention to student feedback and look out for red flags. Don’t rely solely on reviews posted on the course provider’s website. Look to third-party review sites such as Course Report, SwitchUp, Trustpilot, Career Karma, and more for unbiased reviews.
If possible, connect with students who have completed the program and ask them to share their thoughts on the program and what outcomes they achieved post-graduation. Also, check if the course offers statistics on student success rates (i.e. enrollment vs. completion rate, further education, and job placements, if applicable). Statistics that have been compiled and/or verified by a third party are generally more trustworthy.
Schedule and Flexible Learning Options
Most data science courses are designed with working professionals in mind. If you have a full-time job, you’ll want to select courses that can be completed in just a few hours a week. Also, consider if the course is self-paced or if you have to log on for live classes at a specific time. Most short courses are asynchronous and consist mostly of pre-recorded lectures. There’s less interactivity, but this is useful if you’re simply trying to brush up on a specific skill.
Data science is an ever-evolving field. Courses should be updated regularly (at least once a year) to reflect changing industry standards, new technologies, and programming frameworks. Any datasets used for assignments or referenced in course material should be current and up-to-date.
Quality of Instructors
Pay close attention to instructor credentials before enrolling in a course. See how many years of experience they have and determine whether their professional background directly relates to the course content. Course material developed by data science professionals is more likely to be aligned with industry standards.
Most courses have an introductory video you can watch before enrolling. Are the instructors engaging and personable? Do they explain complex topics in simple terms? Another factor to consider is how much interaction you’ll have with instructors versus time spent on self-study. Are there any live classes? Is there a discussion board where you can post questions? Are there graded assignments and, if so, are these assignments graded by the instructors, teaching assistants, or peers? Look for opportunities to have your work reviewed by a seasoned professional.
Prioritize courses that offer opportunities to complete hands-on projects that touch on the entire data science process and use real-world datasets. Are there assignments built into each module so you can apply your knowledge before moving on to the next topic? Assignments should test your comprehension of theoretical concepts and provide exercises to apply your new skills. Graded assignments are the best way to improve your skills because you can receive feedback on your work. A strong portfolio lets you demonstrate your value to an employer and also provides ample discussion material during the interview process.
Beware of courses that offer peer-graded assignments or overemphasize multiple-choice testing because you won’t receive the feedback you need to expand your skill set. On top of practical projects offered during the course, is there any career assistance, or internship/job placement opportunities?
A certificate of completion evinces your skills. While some MOOCs can be audited for free, they do not culminate in certification, so you have no way of proving to an employer that you completed the course.
Making the Most Out of a Data Science Course
Most students find it helpful to pursue additional learning above and beyond the course material. Being active in the data science community, working on personal projects, and practicing your skills on structured and unstructured datasets will help you build the technical and soft skills employers seek the most. Here are some other things to consider if you want to make the most out of your data science course:
What Should You Expect To Learn in a Data Science Course?
Data science courses should teach you the entire data science process, from finding and identifying viable datasets to data cleaning, building and tuning machine learning models, and data visualization. Remember that an estimated 80% of a data scientist’s time is spent cleaning data, so make sure you have a solid foundation in preparing data for staging. If you have no prior experience with popular programming languages, choose a course that provides you with an introduction to Python or R.
The course should also impart statistical techniques for analyzing data and extracting insights from large datasets. Math is foundational to working in data science—especially statistics and probability. You must learn basic mathematical concepts like variance, correlations, conditional probabilities, and Bayes’ theorem. You should also master popular analysis techniques such as cluster analysis, regression, time series analysis, and cohort analysis. The course should teach you how to use popular analytical tools like Hadoop, Hive, and Pig to extract valuable information from a dataset.
Another key aspect of data science is understanding relational databases so you can write query commands to retrieve and store data. Data scientists must become fluent in SQL, one of the most popular database query languages. You need to understand how relational databases work and learn the specific query commands to retrieve and store data. Data science courses should teach learners about industry-recognized data science tools, such as SAS, Apache Spark, D3.js, MATLAB, and more.

A high-quality data science course will also teach you how to use supervised and unsupervised machine learning algorithms such as linear regression, logistic regression, decision trees, and the Naive Bayes algorithm. You should have opportunities to work with both structured and unstructured data to reflect real-world conditions.
Finally, you need to learn how to think like a data scientist. Ultimately, data science is about storytelling. The crux of your work is to communicate your findings to non-technical audiences using language and data visualizations, make recommendations, and shape business decision-making based on your findings. One of the best ways to learn these soft skills is by receiving mentorship from an industry expert who can share tips on how they were able to succeed and help you understand the day-to-day realities of working as a data scientist. Do your research to find the perfect data science course that checks all of these key boxes.
What Will My Schedule Look Like?
Most online courses are self-paced, requiring anywhere from 2-10 hours of study per week. If you decide to enroll in a data science bootcamp instead of a short course, you might need to devote more study time. The average student completes Springboard’s Data Science Career Track in six months at a pace of 20 hours per week. Completion time depends on whether or not you are working full-time and have other commitments outside of your studies.
How Can You Implement What You Learn?
Keep your knowledge fresh by contributing to open-source projects on Github, creating personal projects for your portfolio, volunteering, or finding an internship. Continue practicing your skills using real-world datasets on Kaggle, Google Dataset Search, Data.Gov, Datahub.io, and more. For inspiration, read through documentation or community discussion forums from past data science competitions to find tips on how to work through a problem on your own. Once you feel ready, participate in hackathons on Kaggle, HackerEarth, Machine Hack, and other communities. This will teach you how to work with other engineers or data scientists and tackle real-world problems.
You can also get involved in a data science community to discuss the latest industry news, attend events, access content such as blogs, whitepapers, and webinars, and network with industry professionals. The IBM Data Science Community, Data Science Central, Open Data Science, and Kaggle are just a few examples of highly active data science communities.
