Prerequisite
Descriptive statistics (graphs, mean, variance,cross-table...)
- Random variables
- Expected value, variance, standard deviation
- Usual probability distributions (Normal )
Goal
At the end of the course, the student should be able to:
-use a database and give an estimate for a population parameter (mean, proportion and sdandard deviation),
- compute confidence intervals for a mean or a proportion and perform statistical tests
- analyse and test the relationship between two qualitative or quantitative variables
- determine sample size for the mean and for the proportion
- compare the means of two independent populations
- according to the database, recognize what kind of confidence intervals and statistics tests should be performed
-integrate a group to do a project
Have greater awareness about ESRS topics such as: Capacity to interact and collaborate
with others effectively, including in teams, in the workplace
Be able to argue his hypothesis and analyse his results in a scientific way.
Presentation
Chapter 1: The normal distribution

Chapter 2 : Sampling
-Probability distribution of the sample mean, proportion and standard deviation

Chapter 3: Estimate and confidence intervals
-estimator's properties; CI for the mean when the population variance is unknown; CI for the proportion; margin of error and sample size

Chapter 4: Statistical tests
-one-tail test; two-tail test; p-value

Chapter 5 : Chi-Square test for independence
-use excel to draw a pivot-table
-independency test

Chapter 6: Two-Sample tests

Evaluation
Students have 2 written evaluations that contain exercises, open questions and MCQ. The evaluations do not focus on the calculus and formula. The student have to explain their reasoning and and analyse the result. They also have to do a project for which students have to find a problematic, get a sample and then use all the concepts studied in class.
