Lightning Review: How to Use SPSS

“A nice step-by-step explanation!”

“Easy, not too advanced!”

“A great start!”

           Real, live reviews of Brian C. Cronk’s How to Use SPSS: A Step-By-Step Guide to Analysis and Interpretation by some of our patrons! This book, the Tenth Edition of this nine-chapter text published by Taylor and Francis, is ripe with walkthroughs, images, and simple explanations that demystifies the process of learning this statistical software. Also containing six appendixes, our patrons sang its praises after a two-hour research session here in the Scholarly Commons!

           SPSS, described on IBM’s webpage as “the world’s leading statistical software used to solve business and research problems by means of ad-hoc analysis, hypothesis testing, geospatial analysis and predictive analytics. Organizations use IBM SPSS Statistics to understand data, analyze trends, forecast and plan to validate assumptions and drive accurate conclusions’ is one of many tools CITL Statistical Consulting uses on a day-to-day basis in assisting Scholarly Commons patrons. Schedule a consultation with them from 10 am to 2 pm, Monday through Thursday, for the rest of the summer!

           We’re thrilled to hear this 2018 title is a hit with the researcher’s we serve! Cronk’s book, and so many more works on software, digital publishing, data analysis, and so much more make up our reference collection – free to use by anyone and everyone in the Scholarly Commons!

Love and Big Data

Can big data help you find true love?

It’s Love Your Data Week, but did you know people have been using Big Data for to optimize their ability to find their soul mate with the power of data science! Wired Magazine profiled mathematician and data scientist Chris McKinlay in “How to Hack OkCupid“.There’s even a book spin-off from this! “Optimal Cupid”, which unfortunately is not at any nearby libraries.

But really, we know you’re all wondering, where can I learn the data science techniques needed to find “The One”, especially if I’m not a math genius?

ETHICS NOTE: WE DO NOT ENDORSE OR RECOMMEND TRYING TO CREATE SPYWARE, ESPECIALLY NOT ON COMPUTERS IN THE SPACE. WE ALSO DON’T GUARANTEE USING BIG DATA WILL HELP YOU FIND LOVE.

What did Chris McKinlay do?

Methods used:

  • Automating tasks, such as writing a python script to answer questions on OKCupid
  • Scraping data from dating websites
  • Surveying
  • Statistical analysis
  • Machine learning to figure out how to rank the importance of answers of questions
  • Bots to visit people’s pages
  • Actually talking to people in the real world!

Whether you reach out to us by email, phone, or in-person our experts are ready to help with all of your questions and helping you make the most of your data! You might not find “The One” with our software tools, but we can definitely help you have a better relationship with your data!

Review: The Infographic History of the World by Valentina D’Efilippo and James Ball

The Infographic History of the World, created by Valentina D’Efilippo and James Ball, consists of various infographics with accompanying commentaries. You can find this book and read it at Scholarly Commons, near our other infographic and visualization books! You can also check it out from a nearby library!

Overall, this book is a compelling read and an interesting idea as a project and some of the infographics were really well done. This book demonstrates the power of infographics to help us present and break down important topics to wider audiences. Yes, this isn’t supposed to be a serious read, but there was a lot I did not like about this book, specifically throughout I got a sense that:

  • “The story of the last 4,000 years is one of nations being founded, breaking apart, going to war, and coming together” (D’Efilippo & Ball, 2013). For those confused why this is a problem, “nation” is a very modern term and concept so that’s a serious anachronism.
  • Why is the theocracy symbol notably non-Western and not used for the English Civil War, which was apparently about republicanism?
  • A history of the “Net” that doesn’t mention Minitel.
  • First flight goes to the Wright Brothers. No mention of Santos-Dumont or the controversy (for everyone who noticed that inexplicable early aircraft cameo at this year’s Olympic opening).
  • The book is very Anglo-centric.

Sloppy stats!

 

  • I’m suspicious anytime Luxembourg wins something. Are they really the biggest drinkers or how does their small population make this data less meaningful?
  • “Absolute number of cannabis users by region” Absolute? Really?
  • Overall, not enough information on where and how a lot of the statistics were generated and why we should trust those sources. Yes, there is an appendix on the back that explains this to some extent in tiny text but not helpful for people who just glance at the infographic and assume it’s giving us useful information about the world.

Visualization issues!

 

  • Emphasizing form over function — much like the new Macbooks with so few ports they are practically landlocked — many of the infographics fail to present the information in a way that is appropriate for what they are trying to present. For example, the Mona Lisa paint by numbers probably would have been more effective as a timeline.
    • Maybe I’m just too attached to the idea of timelines being well on a line or perhaps maybe the spiral depicted on the book’s cover art.
    • Some of the infographics have way too many things going on and are trying to make too many points at once.
  • The colors on the mental illness brain are too close (and I can’t imagine how that would look to someone who is colorblind), and there are other examples where the colors are very close and render the infographic pretty, but hard to actually use to learn something from.

Finally, the authors’ claim of “not trying to be political” / “this is just for fun” is no excuse for not being thorough especially with information targeted to the public. Full disclosure or not, artists and journalists still need to be careful because what people see can influence the way they think about things. Infographics are not a neutral presentation of information, certain choices were made, and audiences need to think about who made these choices and why. Not as bad as some of the examples on this Visual Literacy and Infographics blog post, but still problematic. Please, do not be reckless when making infographics!

To learn more how to create infographics of your own check out our Savvy Researcher workshop: Introduction to Infographics Using Piktochart!

If you are an undergraduate interested in conducting research and becoming information and visual literate there is an entire set of classes in the history department for this through SourceLab. Take a look at their schedule or talk to Professor Randolph to learn more!

Book Review: Statistics Done Wrong by Alex Reinhart

One book you can read (but not check out, sorry!) at Scholarly Commons is Statistics Done Wrong: The Woefully Complete Guide by Alex Reinhart, an expansion of the popular website.

Reinhart studied physics as an undergraduate but did a masters  in statistics after realizing problems that misunderstandings of statistics were causing in physics and science as a whole. He is now working on a PhD in statistics at Carnegie Mellon.

I don’t know if this would be the best book for someone who has no background knowledge whatsoever. While the author does a good job at explaining a lot of the concepts, his target audience is people who’ve encountered bad statistics in advanced level research, such as medical studies. This book is a good start for those who want insight into the mind of a statistician, even if their math skills aren’t quite there. Although the book isn’t numbers heavy, I still definitely got lost a few times and had to re-read some of the passages. However, I really like the writing style of the author. All I want is to be able to write and articulate difficult concepts in a way as clear, concise, and even funny as the author.

One of the main takeaways of the book was:

“Scientists may be superhumanly caffeinated, but they’re still human, and the constant pressure to publish means that thorough documentation and replication are ignored”(Reinhart, 2015).

I remember learning about the difficulty that psychologists have faced replicating their results (and glad to hear that they as a discipline are improving their efforts to make sure studies and results can be replicated.) and this book explained a lot of the factors at play. For example, Reinhart discussed statistical power, and how not all journals checked if researchers had enough data to determine if their results were statistically significant in the first place. And the book goes in depth into the various issues that can make finding statistical significance a poor measure of whether a phenomena is occurring or not. Furthermore, while I found the debate about publication bias of studies about publication bias as well as “False-Positive Psychology” by Joseph P. Simmons  (doi:10.1177/0956797611417632) hilarious, I too am now worried about the state of research.

One suggestion from Statistics Done Wrong  is more options for making scientific data more accessible so that people don’t try the same failed methods again and again and can learn from others’ experiences. In other words, ways to share the raw data and software code used, even in studies that did not get published in a journal, before the format they are in becomes obsolete. Even though that’s often a major pain to do. Research Data Service are the best people to talk to for learning more about the efforts on campus for solving this problem. They are  your best bet for learning about ways to store and make scientific data more available.

Another problem mentioned in the book is the overall lack of statistical knowledge and education. Here at Illinois, Scholarly Commons is just one of many resources available. For more specific technical questions, we recommend asking a statistician through consulting services through the statistics department, however, this service costs money unless you get the STAT 427 students during spring semester. There are also some free resources and workshops through ATLAS-CITL and online tutorials through Lynda.

Overall, Statistics Done Wrong is an interesting read and a good starting point for those interested in having a better understanding of what to look out for when using statistics in research and ways to improve the way research is done on a whole.
