When asked simple questions about global trends--what percentage of the world's population live in poverty; why the world's population is increasing; how many girls finish school -- we systematically get the answers wrong. So wrong that a chimpanzee choosing answers at random will consistently outguess teachers, journalists, Nobel laureates, and investment bankers. Professor and TED presenter Hans Rosling, together with his two long-time collaborators,...

In Israel, pilot trainees who were praised for doing well subsequently performed worse, while trainees who were yelled at for doing poorly performed better. It is an empirical fact that highly intelligent women tend to marry men who are less intelligent. Students who get the highest scores in third grade generally get lower scores in fourth grade.And yet, it's wrong to conclude that screaming is not more effective in pilot training, women choose men...

Data is a social phenomenon. This book examines the ways in which we are constantly engaging with data, consciously through the ways in which we provide data about ourselves and without awareness. It analyses the construction and use of statistics by governmental and non-governmental organisations, looking at how statistics are used in social discourse to advance interests and to achieve particular, often political ends. The authors also consider...

Muchas de las investigaciones en el campo de los negocios utilizan variables cuyos datos son de tipo cualitativo o categórico, en las que no es posible la aplicación de las técnicas paramétricas. Ante esta situación, y debido a que no se dan las condiciones para utilizar los métodos de la inferencia estadística, dada la rigidez en su aplicación, los investigadores se ven limitados a desarrollar solamente un análisis descriptivo y de resumen...

Some in the social sciences argue that the same logic applies to both qualitative and quantitative methods. In A Tale of Two Cultures, Gary Goertz and James Mahoney demonstrate that these two paradigms constitute different cultures, each internally coherent yet marked by contrasting norms, practices, and toolkits. They identify and discuss major differences between these two traditions that touch nearly every aspect of social science research, including...

Not knowing statistics can lead to a loss of money, time, and accurate information. What am I looking at? What do these numbers mean? Why? These are frequent thoughts of those who don't know much about statistics. "I'm not a numbers person" is not a good excuse to avoid learning the basics of this essential skill. Are you a person who earns money? Do you shop at the supermarket? Do you vote? Do you read the news? I'm sure you do. Learn to make...

« La pandémie aura démontré que ce sont bien les écrivains de toutes formations et extractions qui sont capables d'éclairer les médecins. D'o la nécessité de bénéficier d'une grande ouverture d'esprit. Raison de plus d'avoir une double formation, littéraire et scientifique, faisant de l'équilibre une quête continue et une constante voulue. Parce que la fracture entre sciences et lettres entrave notre unique cause, la seule qui vaille,...

Quand une mise en œuvre des principes du marché ultralibéral provoque une crise écologique et idéologique précédée par des crises économiques et financières sévères au cours des XIXe et XXe siècles, puis la première véritable crise financière mondiale en 2008, trouvant sa source aux États-Unis, que peut-on penser de ce système politico-social-économique ultralibéral ? Qu'il est celui des plus forts ou plus nantis ? Les banques...
