Get started in data science: 5 steps you can take online for free

From gaining the right skills to acing your first interview, these resources can help put you on the right track

Making a career change is never easy, but few things are more motivating than the prospect of a good salary and a dearth of competition. That's a fair summary of the data science world today, as at least one well-publicized study has made clear, so why not investigate a little further?

There's been a flurry of free resources popping up online to help those who are intrigued learn more. Here's a small sampling for each step of the way.

1. Understand what it is

Microsoft's website might not automatically spring to mind as a likely place to look, but sure enough, a few months ago the software giant published a really nice series of five short videos entitled "Data Science for Beginners." Each video focuses on a specific aspect, such as "The 5 questions data science answers" and "Is your data ready for data science?"

2. Dig a little deeper

If you think you might be interested in a career in data science, you may want to start getting a feel for the lay of the land by tapping into some of the big blogs and community websites out there. The newly revamped OpenDataScience.com is one example; KDnuggets is another useful resource. A recent post on Data Science Central (another good site) lists key accounts to follow on Twitter. KDnuggets suggests some good e-books to read before plunging into a data science career.

3. Learn the ropes

Still interested? Then you're probably going to need to acquire some skills, as Adam Flugel, a data-science recruiter with Burtch Works, noted in an interview earlier this year. DataCamp delivers instruction for both groups and individuals; other online options include Open Source Data Science Masters and this introductory textbook, which is available as a free PDF through a Creative Commons license. KDnuggets has a nice list of its own with other good options.

4. Get a job

There are lots of places to look for data scientist jobs today, including the aforementioned OpenDataScience.com, which has a section dedicated to that purpose. Kaggle has a jobs board of its own, and there are more to be found on Glassdoor and Indeed.com. Correlation One, a site that just launched earlier this year, bills itself as a matchmaker for data scientists and employers.

5. Prepare to impress

Once you get an interview, there's nothing more confidence-building than expert tips for acing it. Look no further than KDnuggets, which has published just what you need in a post entitled, "21 Must-Know Data Science Interview Questions and Answers." Good luck!

HP OfficeJet Pro 8730

A smarter way to print for busy small business owners, combining speedy printing with scanning and copying, making it easier to produce high quality documents and images at a touch of a button.

HP OfficeJet Pro 8730

I've had a multifunction printer in the office going on 10 years now. It was a neat bit of kit back in the day -- print, copy, scan, fax -- when printing over WiFi felt a bit like magic. It’s seen better days though and an upgrade’s well overdue. This HP OfficeJet Pro 8730 looks like it ticks all the same boxes: print, copy, scan, and fax. (Really? Does anyone fax anything any more? I guess it's good to know the facility’s there, just in case.) Printing over WiFi is more-or- less standard these days.

As a freelance writer who is always on the go, I like my technology to be both efficient and effective so I can do my job well. The HP OfficeJet Pro 8730 Inkjet Printer ticks all the boxes in terms of form factor, performance and user interface.

Windows 10 for Business / Dell XPS 13

I’d happily recommend this touchscreen laptop and Windows 10 as a great way to get serious work done at a desk or on the road.

Windows 10 / HP Spectre x360

Ultimately, I think the Windows 10 environment is excellent for me as it caters for so many different uses. The inclusion of the Xbox app is also great for when you need some downtime too!

Mark Escubio

Windows 10 / Lenovo Yoga 910

For me, the Xbox Play Anywhere is a great new feature as it allows you to play your current Xbox games with higher resolutions and better graphics without forking out extra cash for another copy. Although available titles are still scarce, but I’m sure it will grow in time.
