The Data Science Industry: Who Does What

The fine folks at DataCamp, a great site for learning data science right in your browser, have come up with another great infographic. This time it compares some of the many job titles in the data science field.

The infographic lays out the roles and skills needed for the following job titles. Note: not all the job roles can be confused with a data scientist, but all the roles can be important when completing an entire data science project.

  • Data Scientist
  • Data Analyst
  • Data Architect
  • Data Engineer
  • Statistician
  • Database Administrator
  • Business Analyst
  • Data & Analytics Manager

Analytics vs Data Science

The lines between analytics and data science can definitely be very blurry. Different companies might call the same position by two different names, but at their core, they do have some differences.
Below is an infographic from the faculty of the Online MS in Analytics at American University. I think the infographic is accurate.

In my opinion, a true data scientist should spend more time creating and programming new algorithms while a business analyst should spend more time applying existing algorithms.

A couple of notes
  1. Years of Education are not much different, but the academic disciplines are very different. Data Scientists tend to have degrees with more rigorous mathematical training. For me, this is the biggest differentiator.
  2. It appears financial institutions prefer business analysts while the government and colleges prefers data scientists
  3. Surprisingly, Business analyst jobs are projected to grow faster than data scientists (27% to 15%), not sure I totally agree with that!

Data Science Wars: R vs. Python

The great team over at DataCamp, an online site for learning R , has put together another wonderful infographic. This time, the topic is Data Science Wars (R versus Python). This has been a rather hot topic for quite some time. I even wrote about the debate back in 2013, R vs Python, The Great Debate.

DataCamp did an amazing job packing information into the infographic. Honestly, it is impressive they were able to pack so much information into a single infographic. Some of the topics covered are:

  • History
  • Who uses the language?
  • Community
  • Purpose of the language
  • Popularity
  • And way more great stuff

Enough about the description. Have a look for yourself. It is packed with great arguments for your next “R vs Python” debate.

Data Size Matters Infographic

Here is a great infographic from Data Science @ Berkeley. Just how big is a Gigabyte(GB)? Be sure to look all the way to the bottom. It mentions/explains a few of the latest innovations in hard drives, for example: helium, SMR, HAMR. You will have to scroll to the bottom to see what those acronyms mean.

Infogr.am – Awesome Interactive Infographics

Inforgr.am is a website for creating interactive infographics. Strangely, the site is new to me even though nearly 1 million “infograms” have already been created. Here are some of the features:

  • Use more than 30 different chart types
  • Edit data with a built-in spreadsheet
  • Download the infographic
  • Share on all your favorite social sites

Some Good Interactive Infographics on Infogr.am

  • Facebook Dominates Social Media – This infographic uses data to show just how much Facebook dominates.
  • US College Student Tech Profile – students still prefer to take notes in a notebook
  • Social Media Trends Churches must Understand – “Every church should have a website, Facebook page, Twitter account and consider using Instagram and Pinterest!”
  • Colorado School Equality – there is a correlation between free school lunch and poor grades, see the box plot
  • 5 Reasons why you must blog – not very interactive, but contains some good data
  • Nebraska Football Recruiting – just because I like college football

Facebook dominates Social Networking

The Real Data on Facebook vs. Google+ is a great article about the popularity of different social networks. All the big social networks (Twitter, Facebook, Google+, LinkedIn, Pinterests, and even Myspace) are included. If you have ever wondered whether Google+ is dead or not, this article will help you out. After the data was gathered and analyzed, it is clear that Facebook is currently winning the social media battle.

The best part of the article is an interactive infographic. You can change the view of the infographic for different years and different business segments. Here is a direct link to just the Interactive Infographic, Facebook Dominates Social Networking.
