Dattitude: actitud hacia una vida basada en datos | Ignasi Alcalde

Dattitude: actitud hacia una vida basada en datos | Ignasi Alcalde | DataVis | Scoop.it
Todos hemos oído la palabra big data , la cual podríamos traducir como grandes datos, y que bajo ese concepto nos referimos a la recolección , almacenamiento , tratamiento y análisis de enormes repositorios de datos.  Hay un inmenso poder en el big data y su análisis ,  ya que permite a los ejecutivos y empleados innovadores encontrar nuevos nichos de mercado, ajustar la oferta de sus productos, aumentar los márgenes de beneficio…. Parece atractivo pero sin embargo, la captura del valor y el conocimiento que nos proporcionan los datos a partir de información procesable requiere un cambio de paradigma en la cultura de trabajo con los datos , principalmente a nivel empresarial, tal y como indica el informe “Big data and democratisation of decisions” creado por The Economist. La para fomentar la cultura de trabajo con datos las empresas deben  fomentar la  “dattitude” o actitud hacia los datos de sus empleados. Dicho de otro modo deben facilitar a sus empleados acceso a los datos y las

Lies, Damn Lies And The Myth Of Following The Data

Stephen Dale's curator insight, December 7, 2014 6:34 AM

At the risk of stating the obvious, data requires context in order to reveal useful (and accurate) information. Context will typically include:

 

- where the data was sourced

- how and when it was collected

- what (if any) processes have been applied (e.g. normalisation)

- who "owns" the data

- what quality criteria has been applied (e.g. de-duplication,  limits etc.)

 (not a definitive list)

 

The article makes the point that - increasingly - data is being used and interpreted by non-data scientists, and hence the need to carefully examine, and maybe challenge, the results, statistics and conclusions that have been extrapolated from the data. In particular, be wary of  those folks in marketing who try to use data to put their products and services in the best possible light. 

 

As the authors says: "Everybody can use data to tell whatever story you want to tell ....."

Open Data :  datos, transparencia y conocimiento abierto. | Ignasi Alcalde | DataVis | Scoop.it
Hace unos días asistí al Open Knowledge Fest en Berlin organizado por la Open Knowledge Foundation como invitado a participar en una de las sesiones llamada  “enseñando con datos abiertos” . Esta es una de mis pasiones, fomentar el  trabajo con los datos para crear y conocimiento y valor dentro de las comunidades educativas. Open Knowledge es una organización que fomenta el acceso a la información y al conocimiento de forma abierta y directa. El acceso a la información en mi opinión debe  ser clave en nuestra sociedad si queremos crear sociedades mas justas y equilibradas  y aquí es donde el open data juega un papel clave. Según se indica la Wikipedia el concepto datos abiertos (open data, en inglés) es una  práctica que persigue que determinados tipos de datos estén disponibles de forma libre para todo el mundo, sin restricciones de derechos de autor, de patentes o de otros mecanismos de control. Tiene una ética similar a otros movimientos y comunidades abiertos, como el software

What makes a data visualization memorable?

What makes a data visualization memorable? | DataVis | Scoop.it
It's easy to spot a "bad" data visualization -- one packed with too much text, excessive ornamentation, gaudy colors, and clip art. Design guru Edward Tufte derided such decorations as redundant at best, useless at worst, labeling them "chart junk." Yet a debate still rages among visualization experts: Can these reviled extra elements serve a purpose? Taking a scientific approach to design, researchers from Harvard University and Massachusetts Institute of Technology are offering a new take on that debate. The same design elements that attract so much criticism, they report, can also make a visualization more memorable...

The Rice Process's curator insight, November 24, 2014 8:22 AM

infographics present the greatest opportunity to increase the effectiveness of what is being taught. Designing visual representation of information is more than translating words to pictorials.  The construction involves filtering the information, drawing relationships, revealing patterns and representing the information as meaningful content.

Visualización de datos: el diseño de la comprensión. | Ignasi Alcalde | DataVis | Scoop.it
Se trata de mostrar los datos de manera que permitan comprender la relación que existe entre la evolución de las variables en el tiempo, las tendencias ... y para ello es importante refinar la construcción visual y escoger el tipo adecuado para cada caso, y aquí es donde la forma de gráfico elegido debe ir en función de la necesiadad de conocimiento a transmitir con los datos. Básicamente, una representación visual de datos debería dar a conocer los datos, provocar la reflexión y permitir la comparación de datos, y no distorsionar la impresión sobre los resultados.La magia de visualización de datos , radica en la captura y síntesis previa de la información para mediante el uso de diversas técnicas visuales como diagramas, gráficas, esquemas, conexiones, grafos… para posteriormente transformarla y con ello para facilitar la compresión de la misma. Tener éxito en la visualización de datos que no es otra cosa que dominar el diseño de la comprensión.

Knowledge & life turning today into a (google) search. Algorithms are key!  

Stephen Dale's curator insight, March 26, 2014 4:35 AM

"We are in the era of the algorithm. They decide what news we will see, they decide which person is important and they will even merge more and more into our non-digital lives.

 

But the biggest and realest danger lies in us. If we believe that there is only one truth and that is the one generated by a black-box algorithm we might be deceived easily."

 

A reminder, then, that algorithm's should not take the place of critical thinking.

We need to enlighten users by guiding them through the complexity, using stories and design.
