Creating Good Data

Beschreibung

Create good data from the start, rather than fixing it after it is collected. By following the guidelines in this book, you will be able to conduct more effective analyses and produce timely presentations of research data.

Data analysts are often presented with datasets for exploration and study that are poorly designed, leading to difficulties in interpretation and to delays in producing meaningful results.  Much data analytics training focuses on how to clean and transform datasets before serious analyses can even be started. Inappropriate or confusing representations, unit of measurement choices, coding errors, missing values, outliers, etc., can be avoided by using good dataset design and by understanding how data types determine the kinds of analyses which can be performed.

This book discusses the principles and best practices of dataset creation, and covers basic data types and their related appropriate statistics and visualizations. A key focus of thebook is why certain data types are chosen for representing concepts and measurements, in contrast to the typical discussions of how to analyze a specific data type once it has been selected.

You will:

• Be aware of the principles of creating and collecting data
• Know the basic data types and representations
• Select data types, anticipating analysis goals
• Understand dataset structures and practices for analyzing and sharing
• Be guided by examples and use cases (good and bad)
• Use cleaning tools and methods to create good data

Who This Book Is For

Researchers who design studies and collect data and subsequently conduct and report the results of their analyses can use the best practices in this book to produce better descriptions and interpretations of their work. In addition, data analysts who explore and explain data of other researchers will be able to create better datasets.

“The book is definitely valuable and anyone involved in statistical studies would do well to read it. The text could also be a useful tool in a graduate analysis course. The writing is clear and to the point, with no unnecessary ‘preaching’.” (James Van Speybroeck, Computing Reviews, September 2, 2021)
