*Freakonomics*, and makes his professional association with Steven Levitt known frequently. What comes out is a repetitive book on applied mathematics fleshed out with anecdotes and descriptions of research. It's okay, but nothing groundbreaking.

Fascinating look at the role of statistics and data sets today. Although the book was first published in 2007, the information still seems to be very relevant and up-to-date.

I loved the quiz on p. 113 that tested a person's ability to make unbiased estimates. It's shocking how inaccurate and overconfident I was with my own estimates.

Overall, I thought this was a well-written and researched book that really opens my eyes to the predictability of our world based on statistical data regression. It'...more

I've noticed a theme in my reading lately. I'm apparently getting fed up with learning just how poorly our intuitions work (Incognito: The Secret Lives of the Brain, Predictably Irrational: The Hidden Forces That Shape Our Decisions, etc.) and am looking for ideas about how to overcome those fallibilities. So I read a couple of books by Dr. Nortin M. Hadler and learned about how much medicine & health care rely on bad science....more

people who want to be in the know about cutting-edge data analysis techniques and uses

This was quite an interesting book about the field of data mining, from a very applications perspective. In other words, it was not technical at all. Ayres explained a few mathematical concepts that are fundamental to "number crunching", but he did so in a simple and non-intimidating way. The book was clearly written not for scientists or engineers, but for social scientists and businesspeople who would benefit from doing extensive analysis of their data. Ayres is actually quite passionate about...more

The four interesting things I found in it:

1. The author went over a study done on Greyhound racing, experts vs. a computer model for predicting the winner. All the experts lost and the computer model make a 25% profit. My question: this is a freaking money machine! Why would you ever publish this study? Why not just capitalize on it? Something fishy was definitely going on.

2. All the way at the end of the book he goe...more

I have a near compulsion to look for trends in everything with the goal of forecasting future outcomes. I study patterns looking to predict what will happen next. I loved Mario Livio’s book, The Golden Ratio: The Story of PHI, the World's Most Astonishing Number, am fascinated by the Fibonacci sequence and the study of probabilities. I guess I’m a manqué statistician at heart.

Although I enjoyed this book, I did have hi...more

__The World is Flat__by Thomas Freidman. Immediately, I made a mental note to find and read this book about the impact of computing power on everyday lives. Algorithms, formulas, yikes! (I have a bit of a math phobia.) Thank goodness this book breaks down complex ideas into understandable and applicable explanations.

A wide variety of stories about how the computer is enabling huge changes in our schools, businesses, purchases...more

While a lot of this book was stuff that I was somewhat familiar with (e.g., A/B and multivariate testing) there was enough new materials and insights in here to make this a highly-recommended read. We're moving more and more into a data-driven culture and the people who understand that will be at a big advantage over those who don't. In other words, avoid reading Super Crunchers at your own peril. :)

It should be no surprise that statistics provides some immensely powerful tools. The Internet is chock-full of ingenuitive applications of statistics—from Am...more

Ayres makes the argument for how evidence-based outcomes based on large controlled datasets are the way of the future. He provides a broad range of examples in education, health, and politics.

The first part of the book he does a nice job talking about how technology has made this new movement possible. He talks about needing more Super Crunching in all avenues despite the how difficult and expensive execut...more

It helps you understand while data-driven decision making is important and how businesses today are taking decisions based on data. The data could either be lying in the data warehouse which can be mined for insights or in other case the data is not readily available but c...more

But I found the author to be incredibly annoying to read. It seems like he attended the Malcolm Gladwell School of Coining Cute Phrases to Describe Simple Concepts. He makes up the phrase "Super Cruncher", then proceeds to use it ad nauseum. I picked a...more

the "statistically uninitiated," as the author calls them

An interesting, if repetitive, book about the practical applications of statistics, ranging from business to government policy, from law to internet searches. It contains a large number of fascinating (and occasionally horrifying) pieces of information, enough to satisfy a basic curiosity about how statistics are revolutionizing decision-making in fields as diverse as Hollywood blockbuster filmmaking and poverty reduction, but not enough to really appeal deeply to those who already use statistic...more

Written by Yale Law School professor and econometrician Ian Ayres, Super Crunchers introduces us to huge amounts of data that have been collected and shows us how these statistics can be used to make accurate predictions about everyday things. Some of the examples Ayres uses are how these scores of...more

*how*these numbers are crunched, just how the results can be used. The only thing I learned here was the concept of "making your own data" using randomized t...more

The cheesy subtitle makes it sound like a bad self-help book, but it's really a good, broad overview of the different ways that people are starting to use statistics more heavily in their decision-making. Basically, he explains that people are able to collect and store loads more data than ever before, so the "Super Crunchers" are fitting very accurate equations to the data -- and many of their formulas are better at making accurate predictions than season...more

The work takes a bullish attitude towards data-mining techniques and applications. It is claimed that big data means quick profits for all, but problems are swept under the carpet until late chapters. All that glistens isn't gold. Making it easier to satisfy short-term de...more

geek already, and this book stated a lot of the obvious for me; using

data and performing statistical analysis of that data enables

corporations, and people to make better informed decisions. Throughout

the book he gives various examples of different businesses and people

using data to make better decisions.

He, for example, gives an example of how Monster.com provided random

variations of their website to visitors of their site, and based on

the number of click...more

The basic, and sometimes depressing argument, is that expertise rarely outperforms or even matches a good regression or randomized A/B test. As computing power and storage space ge...more
