Data Scientist Job Analysis

A few weeks ago, I posted 16 Companies Hiring Data Scientists Right Now. I decided to do a bit of analysis on the job posts, so I took all the job posting and compiled them into one file.

The Problem

I wanted to determine 2 things:

  1. What words occurred most often in the job posts?
  2. What words occurred in the most jobs posts?

The questions are similar, but if you read closely, they are different.   I wrote some Java code to answer those questions. The raw results are posted here.


Honestly, nothing too surprising showed up. Not counting the common English words (and, to), the word data was the most popular. It occurred 167 times and it occurred at least once in all 16 job postings. That makes sense; a data scientist should know about data. I thought hadoop would occur in all job descriptions but it only appeared in 11 of the 16 job descriptions. Here are some other words I found interesting:

  • statistical occured 29 times and in 10 job descriptions
  • analysis occured 46 times and in 13 job descriptions
  • analytics occured 22 times and in 6 job descriptions
  • statistics occured 16 times and in 9 job descriptions
  • machine learning occured 14 times and in 9 job descriptions
  • phd occured 11 times and in 11 job descriptions
  • sql occured 12 times and in 10 job descriptions

On an interesting note, Python and R occurred in more job postings than Java (2 more to be exact).

Does anything in the results strike you as interesting?

Highlights of the White House BigData Research Initiative

Yesterday’s announcement included a few main highlights:

  • NIH will make 200TB of human genetic variation data freely available on Amazon Web Services
  • NSF will provide $2M in support of undergraduate education for studying graphical and visualization techniques of bigdata
  • DoD will announce some prize competitions in the coming months
  • Numerous other projects to increase data analysis across the US Government

Here is one note I did find interesting (or funny).  One of the speakers mentioned the need for workers with bigdata skills.  He mentioned the workforce needs 159,000 workers with data skills.  Then a couple minutes later he mention a need for data savvy managers.  He mentioned the workforce will need 1,500,000 managers with data knowledge.   I just thought those 2 numbers did not match up well.

Here are a few more links to other articles summarizing the Research Initiative:

White House is Announcing $200M BigData Research Initiative

Later today (2-3:45 pm ET), the White House will announce a $200M BigData research Initiative. Appropriately, it is being named the “Big Data Research and Development Initiative.”

The announcement will be broadcast live on Science360.

See this PDF for a listing of bigdata projects within the US Government.

I am excited to see how this will affect the education and training of data scientists.
What are your thoughts? Is this a good idea?

List of Free Courses Online

Having trouble keeping track of what schools offer what courses for free online? Problem solved!

Class Central maintains a updated list of courses from Coursera(Stanford), Udacity, MITx, and others as they become available. Not all of the courses are related to data science, but I still thought it was valuable to share the link.

Check it out and start learning.

Use Data Science to Help The World (Data Without Borders)

Data Without Borders

Jake Porway started Data Without Borders because he attended a hack-a-thon and the groups came up with apps that didn’t really better the world very much. I believe he used the word, “unfulfilling” to describe the apps. He decided to create a way to provide organizations (Government or non-profit) with access to data scientists. His thinking goes like this. There are lots of data scientists that love to work with data. There are great organization with lots of data. If the two can be matched together, what amazing things can be done? Data Without Borders hopes to find out.

Data Without Borders organizes a bunch of DataDives, which are weekend hack-a-thons that match up a group of data scientists and developers with data.

Jake concluded with some wonderful remarks:

What if we started using data not just to make better decisions about what kind of movies we wanted to see? What if we started using data to make betters decisions about what kind of a world we wanted to see?

What is Data Without Borders looking for?

Think Stats – An Online Statistics Book For Programmers

Previously I mentioned that online statistics learning resources are not abundant.

Well, here is a new online book for learning statistics. It is geared towards programmers, and it looks to be a great fit for people wanting to learn data science.  Here is a small excerpt from the Preface:

It emphasizes the use of statistics to explore large datasets.

I have only had time to quickly browse the book, but it looks quite good.
