This statistics and data analysis course will pave the statistical foundation for our discussion on data science.

You will learn how data scientists exercise statistical thinking in designing data collection, derive insights from visualizing data, obtain supporting evidence for data-based decisions and construct models for predicting future trends from data.

• Data collection, analysis and inference
• Data classification to identify key traits and customers
• Conditional Probability-How to judge the probability of an event, based on certain conditions
• How to use Bayesian modeling and inference for forecasting and studying public opinion
• Basics of Linear Regression
• Data Visualization: How to create use data to create compelling graphics

Best Review

J'ai beaucoup aimé ce MOOC Il est à la fois accessible et permet d'acquérir des notions assez pointues. Il demande suffisamment de travail pour que l'obtention du certificat soit perçu comme une victoire. Et ça faisait longtemps que j'avais pas éprouvé autant de plaisir à en terminer un ! Sur le contenu, il s'agit surtout de l'exploration de quelques champs d'applications des statistiques modernes. L'analyse de texte, la génomique, le big data évidemment, et d'autres domaines tout aussi passionnants. Compter environ 3 heures par semaine pour des techophiles maîtrisant l'anglais. Le double pour les autres. Mais le jeu en vaut la chandelle !
