Aims
- to understand and to explain the concepts studied
- to recognise the kind of method to be used for a given problem
- to use each tool and to apply it in various situations
- to follow a systematic process to resolve a problem, from the choice of the method, its application, its validation up to the interpretation of the obtained results
- to have a good view of the fields of application of statistics in psychology and of the situation he will have to face
- to have a good view of the fields of application of statistics in psychology and of the situation he will have to face
Main themes
- graphic and numeric tools to summarise the available information about one or two qualitative and/or quantitative variables: frequency tables, bar charts, histograms, distribution,
box-plots, mean, variance, standard deviation, correlation coefficients (Pearson, Kendall and Spearman), X-Y graphs, etc.
Probability:
- definition of probability, basic combinatory calculation, formulas for basic probability calculation, independence, conditional probability, Bayes theorem, discrete and continuous random variables, uniform, binomial and normal distribution, central limit theorem
Statistical inference:
- notions of estimation, confidence interval and hypothesis tests. Inference on the means and variances of one or two normal populations and on one or two proportions.
Content and teaching methods
- the last part will present the basic concepts of statistical inference: notions of estimation, confidence interval and hypothesis tests are explained and applied to the inference on the means and variances of one or two normal populations and on one or two proportions.
Methods: Lectures and exercises. The exercises are in small groups and are guided by assistants.
