Statistics

Basic part (5 credits): Descriptive statistics. Probability of events, combinatorics and conditional probability. Stochastic variables, expectation and variance. Covariance, correlation and independence. Common probability distributions (e.g., binomial, poisson, exponential and normal distribution). The central limit theorem. Parameter estimation and confidence intervals. One-sample hypothesis tests. Simple linear regression.

Special part (2.5 credits): Experimental design: Two-factor experimental design, block pairing, analysis of methods for repeated and non-repeated experiments. Statistical quality control: Sources of variation, random sampling, control charts for expected values, standard deviations and count data, and capability indexes.

Knowledge

The candidate is familiar with the basic ideas in probability and statistics. The candidate has knowledge about simple statistical models and processes that are often used within their field of study. The candidate knows how to use statistics in a comprehensive way and understands that statistics is a necessary tool for measuring, describing and evaluating results. The student also knows how to use basic statistical inference methods to describe processes and populations based on independent trials and random samples. The candidate has knowledge of experimental design and statistical process control.​

Skills

The candidate can

• present and describe the characteristics of a data material using descriptive statistics, tables and figures
• calculate the probability of events and conditional probabilities, using e.g. combinatorics, stochastic variables, the most common probability distributions (e.g., binomial, poisson, exponential and normal distribution) and the central limit theorem.
• perform simple methods for statistical inference such as parameter estimation, confidence intervals, one-sample hypothesis tests, correlation and simple linear regression
• apply statistical principles and concepts in his/hers professional field
• use Python, or a similar statistical software, to perform basic statistical analysis
• perform and analyse two-factor experiments, and interpret results from statistical analysis related to experimental design and statistical process control

General competence

The candidate sees the importance of statistical knowledge and expertise in the engineering role and is able to communicate with professionals about engineering problems by using statistical concepts and expressions. The candidate has gained confidence in simple statistical analysis, two-factor experiments and statistical process control through student activities such as exercises and project work. This competence provides a platform for further engineering studies, and for various types of applications in industry, consulting and the public sector.

Lectures, collaborative project work and exercises.

Supplemental information for internet-students: Lectures may be streamed from Gjøvik, and will also be available from the LMS afterwards. Supervision will be done both using real time technology and using a digital forum. Compulsory attendance in person at Gjøvik for the final exam.
