Shron - Thinking with Data

" Thinking with Data gets to the essence of the process, and guides data scientists in answering that most important questionwhats the problem were really trying to solve?

Thinking with Data does a wonderful job of reminding data scientists to look past technical issues and to focus on making an impact on the broad business objectives of their employers and clients. Its a useful supplement to a data science curriculum that is largely focused on the technical machinery of statistics and computer science.

This is a great piece of work. It will be required reading for my team.

Shrons Thinking with Data is a nice mix of academic traditions, from design to philosophy, that rescues data from mathematics and the regime of pure calculation. These are lessons that should be included in any data science course!

Working with data is about producing knowledge. Whether that knowledge is consumed by a person or acted on by a machine, our goal as professionals working with data is to use observations to learn about how the world works. We want to turn information into insights, and asking the right questions ensures that were creating insights about the right things. The purpose of this book is to help us understand that these are our goals and that we are not alone in this pursuit.

I work as a data strategy consultant. I help people figure out what problems they are trying to solve, how to solve them, and what to do with them once the problems are solved. This book grew out of the recognition that the problem of asking good questions and knowing how to put the answers together is not a new one. This problemthe problem of turning observations into knowledgeis one that has been worked on again and again and again by experts in a variety of disciplines. We have much to learn from them.

People use data to make knowledge to accomplish a wide variety of things. There is no one goal of all data work, just as there is no one job description that encapsulates it. Consider this incomplete list of things that can be made better with data:

Doing each of these well in a data-driven way draws on different strengths and skills. The most obvious are what you might call the hard skills of working with data: data cleaning, mathematical modeling, visualization, model or graph interpretation, and so on.[]

What is missing from most conversations is how important the soft skills are for making data useful. Determining what problem one is actually trying to solve, organizing results into something useful, translating vague problems or questions into precisely answerable ones, trying to figure out what may have been left out of an analysis, combining multiple lines or arguments into one useful resultthe list could go on. These are the skills that separate the data scientist who can take direction from the data scientist who can give it, as much as knowledge of the latest tools or newest algorithms.

Some of this is clearly experienceexperience working within an organization, experience solving problems, experience presenting the results. But these are also skills that have been taught before, by many other disciplines. We are not alone in needing them. Just as data scientists did not invent statistics or computer science, we do not need to invent techniques for how to ask good questions or organize complex results. We can draw inspiration from other fields and adapt them to the problems we face. The fields of design, argument studies, critical thinking, national intelligence, problem-solving heuristics, education theory, program evaluation, various parts of the humanitieseach of them have insights that data science can learn from.

Data science is already a field of bricolage. Swaths of engineering, statistics, machine learning, and graphic communication are already fundamental parts of the data science canon. They are necessary, but they are not sufficient. If we look further afield and incorporate ideas from the softer intellectual disciplines, we can make data science successful and help it be more than just this decades fad.

A focus on why rather than how already pervades the work of the best data professionals. The broader principles outlined here may not be new to them, though the specifics likely will be.

This book consists of six chapters. , to give you places to go from here.
