Netflix, the king of Video On Demand platforms, represents a clear example of a data-driven company. And the thing is that Netflix, not only has managed to break through and succeed in the film and television industry, but through a disruptive business model and idea has also changed the rules of the game and has revolutionized this entire sector. To date, the film or motion picture industry has been governed by the production of similar content among different companies (including editing remakes after remakes), following the same business models over and over again and living as revolutions and innovations only an update of formats (sale / rental VHS, DVDs, Blu-rays, analog, digital format, Full HD, 4K …), while the business model remained based on high market access times controlled by the industry and not by users (for example, with content releases with up to 1 year difference between different countries).

Following up on the information presented in the post “Descriptive Statistics”, below, we will know the most basic ways to visualize the data or information to be analyzed. Specifically: Pie chart Line chart Treemap & Subburst Histograms & Bar charts Density plot Boxplots Violin plots Scatter plots Pareto chart Note: All the examples (except for the line graphs due to its features) are based on the train.csv dataset file, which is a subset of 891 representative individuals of the population of the Titanic used for the training of models of Machine Learning.

Despite the fact that nowadays, for the great majority of people, the name of John Snow brings to his mind to Aegon Targaryen or the heir to the iron throne, there is actually another, perhaps less popular, John Snow (United Kingdom 15/03/1813 - 16/06/1858). This another John Snow should be known as a precursor or forerunner of epidemiology and geolocation and one of the references in the field of dissemination of data thanks to its Cholera map of 1854.

Spreadsheet tools as Microsoft Excel, Google Spreadsheet, Apache OpenOffice Calc (see other alternatives in maketecheasier) could be considered as a basic or introductory tool for data analysis. In this post, we are going to focus on the tool MS Excel 2016 as a basic introduction to several of its more interesting functionalities for data analysis (in a similar way found in the other spreadsheet tools). In later entries of the Project section, practical examples developed with these features will be shown. [Read More]

As a starting point in data analysis, it is necessary to know some mathematical and statistical foundations in order to work with the information to be analyzed. Thus, we will start learning some basic concepts: Population, Samples, Individuals and Variables: Population: The set of all the elements under study Sample: A subset of elements of the population (it should be representative of the population) Individuals: Every individual element in the popularion Variables: Characteristics of the individuals Example: Titanic Dataset [Read More]

As a first step in the data science learning track, and inside the Microsoft Virtual Academy, you can find the Microsoft Professional Program for Data Science course delivered through the online learning platform edX. How it works? This program, certified by Microsoft, is made up of 3 units with 10 courses (lasting about 8-12 hours each) and a project capstone. The Microsoft Program Certificate is achieved once all the courses have been verified and certified through the edX platform (in case of not being interested in this certification and as for the rest of MOOCs in the edX platform, they can also be done free of charge).
