#### Description du cours

Statistics play an important role in management decision making. Good decisions are based on an accurate description of the observed data. Relevant strategies rely on modeling data and estimating the parameters of the model using data. Only decisions that are motivated by appropriate statistical analysis may be convincing and broadly accepted.

The aim of this course is to introduce basic notions and methods in statistics. In this course you will learn how to describe data using sample measures and graphical tools, how to model data using notions of probability such as random variables and population measures, how to estimate model parameters using point estimates and confidence intervals, how to test hypotheses concerning model parameters using testing procedures and how to measure the relationship between two or more variables using regression analysis.

Statistical methods are introduced through a mathematical framework, combined with illustrations using Excel and applications to management data. A large set of exercises with solutions and electronic self-review tests are also provided.

#### Avis des utilisateurs

##### excellent course

Very well organized course, hence easy to follow. I enjoyed the connections with real life events like the story of Moneyball or the Challenger disaster. The self-review tests and the problem sets with complete solutions are of great use to understand the statistical techniques in the corresponding topics.

##### super cool course

As a biz student, I have struggled with statistics for yrs. Just couldn't get what the fuss was all about. After watching this course, stats are finally starting to make sense for me. There are lots of neat real-world examples, like google, facebook and moneyball. Prof. Czellar gives crystal clear explanation and has a great sense of humor. She is also an IT wizard. AWSOME!!!
