Schedule, syllabus and examination date

Choose semester

Course content

The course gives a basic introduction to probability and the use of probability models to describe random variables and stochastic processes. The course also gives an introduction to statistical inference, that is how to extract information from data. The course gives a good background for STK1110 – Statistical methods and data analysis

Learning outcome

After having completed the course:

  • You know about the concept of probability and master the basic rules of probability.
  • You know about random variables, and are able to find expectation, variance, covariance and moment generating functions.
  • You know about the most common univariate probability models, and have seen examples of bivariate models.
  • Are you able to do computations with univariate and bivariate distributions and to determine conditional distributions.
  • You know about the law of large numbers and the central limit theorem.
  • You know methods for estimation and construction of confidence intervals in some simple situations.
  • You know about stochastic simulation and bootstrapping.


Students who are admitted to study programmes at UiO must each semester register which courses and exams they wish to sign up for in Studentweb.

If you are not already enrolled as a student at UiO, please see our information about admission requirements and procedures.


Formal prerequisite knowledge

In addition to fulfilling the Higher Education Entrance Qualification, applicants have to meet the following special admission requirements:

  • Mathematics R1 (or Mathematics S1 and S2) + R2

And in addition one of these:

  • Physics (1+2)
  • Chemistry (1+2)
  • Biology (1+2)
  • Information technology (1+2)
  • Geosciences (1+2)
  • Technology and theories of research (1+2)

The special admission requirements may also be covered by equivalent studies from Norwegian upper secondary school or by other equivalent studies (in Norwegian).

Recommended previous knowledge

MAT1100 – Calculus and MAT-INF1100 – Modelling and computations.

Overlapping courses

4 credits overlap with ECON2130 – Statistikk 1

*The information about overlaps for discontinued courses may not be complete. If you have questions, please contact the Department. 


4 hours of lectures and 2 hours of problem solving in plenum per week. In addition there will be exercise solving groups/datalabs during the week, with guidance.

The number of groups offered can be adjusted during the semester, depending on attendance.


2 mandatory assignments.

A written digital midterm exam and final written digital examination at the end of the semester add up to the final grade. Both exams are compulsory and have to be taken in the same semester.

Midterm exam counts for 1/3 and the final examination counts for 2/3. The final grade is based on the total score and a general impression after the final examination.

Examination support material

Approved calculator and formula list for STK1100/ STK1110.

Language of examination

You may write your examination paper in Norwegian, Swedish, Danish or English.

Grading scale

Grades are awarded on a scale from A to F, where A is the best grade and F is a fail. Read more about the grading system.
