Course Content

This course provides an introduction to and foundation for statistical analysis.
This course also introduces use of statistical software (students can individually opt for either SPSS or R).
Topics covered in the lectures and WPOs:
Probability theory
• Combinatorics
• Probability models: simulation and theoretical
• Classical definition of probability versus frequential definition
• Basic rules of probability theory
o Summation theorem
o Conditional probabilty
o Product rule
o Bayes' rule
Stochastic variables
• Discrete
• Continuous (area under the curve)
Sampling distributions
• Sampling distributions for numbers and proportions
o Sampling with and without replacement
o Binomial distributions
o Normal approximation of binomial distribution
o Continuity correction
• Sampling distribution of sample means
o Expected value and standard deviation of sample means
o Central limit theorem
Introduction to Statistical Inference
• Reliable estimation
o Point estimates
- Maximum Likelihood
Pure and impure estimators
o Confidence intervals
o Determining a required sample size
• Significance tests
o z test

Statistical software:
Students choose either R or SPSS for themselves. Introduction to the software opted for largely consists of self-study using a instructive reader, supplemented with a number of classical exercises sessions and guided self-study (break-out rooms in the presence of a teacher).

Script or syntax-based data-analysis is instructed and required.

Learning Outcomes

General Competences

Apart from a very thorough knowledge of the theory, it is mainly expected that the student can independently apply the learned techniques to realistic data and use them to solve presented problems.

Explain examples of probability models

Apply the laws of probability

Explain a "sampling distribution"

Create and interpret confidence intervals

Explain and motivate the reasoning for significance tests

Performing and interpreting a z-test on sample means and reporting in APA style

Grading

The final grade is composed based on the following categories:
Written Exam determines 70% of the final mark.
Practical Exam determines 30% of the final mark.

Within the Written Exam category, the following assignments need to be completed:

Written exam: theory with a relative weight of 70 which comprises 70% of the final mark.

Within the Practical Exam category, the following assignments need to be completed:

Practical exam: software with a relative weight of 30 which comprises 30% of the final mark.

Additional info regarding evaluation

70% Written exam
30% Practical exam: software

If a student does not participate to both parts, the end grade will be an "absent".

Allowed unsatisfactory mark

The supplementary Teaching and Examination Regulations of your faculty stipulate whether an allowed unsatisfactory mark for this programme unit is permitted.
