New Survey Technique! Ask Village Idiots

Thursday, April 30th, 2015

I was deeply disappointed to see Scientific Computing with the headline: ‘Avengers’ Stars Wary of Artificial Intelligence by Ryan Pearson.

The respondents are all talented movie stars but acting talent and even celebrity doesn’t give them insight into issues such as artificial intelligence. You might as well ask football coaches about the radiation hazards of a possible mission to Mars. Football coaches, the winning ones anyway, are bright and intelligent folks, but as a class, aren’t the usual suspects to ask about inter-planetary radiation hazards.

President Reagan was known to confuse movies with reality but that was under extenuating circumstances. Confusing people acting in movies with people who are actually informed on a subject doesn’t make for useful news reporting.

Asking Chris Hemsworth who plays Thor in Avengers: Age of Ultron what the residents of Asgard think about relief efforts for victims of the recent earthquake in Nepal would be as meaningful.

They still publish the National Enquirer. A much better venue for “surveys” of the uninformed.

Speaking of Numbers and Big Data Disruption

Survey: Big Data is Disrupting Business as Usual by George Leopold.

From the post:

Sixty-four percent of the enterprises surveyed said big data is beginning to change the traditional boundaries of their businesses, allowing more agile providers to grab market share. More than half of those surveyed said they are facing greater competition from “data-enabled startups” while 27 percent reported competition from new players from other industries.

Hence, enterprises slow to embrace data analytics are now fretting over their very survival, EMC and the consulting firm argued.

Those fears are expected to drive investment in big data over the next three years, with 54 percent of respondents saying they plan to increase investment in big data tools. Among those who have already made big data investments, 61 percent said data analytics are already driving company revenues. The fruits of these big data efforts are proving as valuable as existing products and services, the survey found.

That sounds important, except they never say how business is being disrupted? Seems like that would be an important point to make. Yes?

And note the 61% who “…said data analytics are already driving company revenues…” are “…among those who have already made big data investments….” Was that ten people? Twenty? And who after making a major investment is going to say that it sucks?

The survey itself sounds suspect if you read the end of the post:

Capgemini said its big data report is based on an online survey conducted in August 2014 of more than 1,000 senior executives across nine industries in ten global markets. Survey author FreshMinds also conducted follow-up interviews with some respondents.

I think there is a reason that Gallup and those sort of folks don’t do online surveys. It has something to do with accuracy if I recall correctly. 😉

analyze survey data for free

Friday, October 24th, 2014

Anthony Damico has “unlocked” a number of public survey data sets with blog posts that detail how to analyze those sets with R.

Forty-six (46) data set are covered so far:

unlocked public-use data sets

An impressive donation of value to R and public data and an example that merits emulation! Pass this along.

I first saw this in a tweet by Sharon Machlis.

Data + Design

Data + Design: A simple introduction to preparing and visualizing information by Trina Chiasson, Dyanna Gregory and others.

From the webpage:

ABOUT

Information design is about understanding data.

Whether you’re writing an article for your newspaper, showing the results of a campaign, introducing your academic research, illustrating your team’s performance metrics, or shedding light on civic issues, you need to know how to present your data so that other people can understand it.

Regardless of what tools you use to collect data and build visualizations, as an author you need to make decisions around your subjects and datasets in order to tell a good story. And for that, you need to understand key topics in collecting, cleaning, and visualizing data.

This free, Creative Commons-licensed e-book explains important data concepts in simple language. Think of it as an in-depth data FAQ for graphic designers, content producers, and less-technical folks who want some extra help knowing where to begin, and what to watch out for when visualizing information.

As of today, the Data + Design is the product of fifty (50) volunteers from fourteen (14) countries. At eighteen (18) chapters and just shy of three-hundred (300) pages, this is a solid introduction to data and its visualization.

The source code is on GitHub, along with information on how you can contribute to this project.

A great starting place but my social science background is responsible for my caution concerning chapters 3 and 4 on survey design and questions.

All of the information and advice in those chapters is good, but it leaves the impression that you (the reader) can design an effective survey instrument. There is a big difference between an “effective” survey instrument and a series of questions pretending to be a survey instrument. Both will measure “something” but the question is whether a survey instrument provides you will actionable intelligence.

For a survey on any remotely mission critical, like user feedback on an interface or service, get as much professional help as you can afford.

When was the last time you heard of a candidate for political office or serious vendor using Survey Monkey? There’s a reason for that lack of reports. Can you guess that reason?

Computer Science – Know Thyself!

Friday, August 22nd, 2014

Putting the science in computer science by Felienne Hermans.

From the description:

Programmers love science! At least, so they say. Because when it comes to the ‘science’ of developing code, the most used tool is brutal debate. Vim versus emacs, static versus dynamic typing, Java versus C#, this can go on for hours at end. In this session, software engineering professor Felienne Hermans will present the latest research in software engineering that tries to understand and explain what programming methods, languages and tools are best suited for different types of development.

Great slides from Felienne’s keynote at ALE 2014.

I mention this to emphasize the need for social science research techniques and methodologies for application development. Investigation of computer science debates with such methods may lead to less resistance to them for user facing issues.

Perhaps a recognition that we are all “users,” bringing common human experiences to different interfaces with computers, will result in better interfaces for all.

A course in sample surveys for political science

Saturday, January 18th, 2014

A course in sample surveys for political science by Andrew Gelman.

From the post:

A colleague asked if I had any material for a course in sample surveys. And indeed I do. See here.

It’s all the slides for a 14-week course, also the syllabus (“surveyscourse.pdf”), the final exam (“final2012.pdf”) and various misc files. Also more discussion of final exam questions here (keep scrolling thru the “previous entries” until you get to Question 1).

Enjoy! This is in no way a self-contained teach-it-yourself course, but I do think it could be helpful for anyone who is trying to teach a class on this material.

An impressive bundle of survey material!

I mention it because you may be collecting survey data or at least asked to process survey data.

Hopefully it won’t originate from Survey Monkey.

If I had $1 for every survey composed by a statistical or survey illiterate on Survey Monkey, I could make a substantial down payment on the national debt.

That’s not the fault of Survey Monkey but there is more to survey work than asking questions.

If you don’t know how to write a survey, do us all a favor, make up the numbers and say that in a footnote. You will be in good company with the piracy estimators.
