NBIK14016U Experimental Design and Statistical Methods in Biology (StatBio)
BSc Programme in Biology
MSc Programme in Biology
MSc Programme in Biochemistry
The course is intended to give a broad overview of experimental designs and statistical methods in order for students to plan their own experiments and to analyze existing data. Students are recommended to follow the course shortly before they start their bachelor project, their M.Sc. thesis project, or as a part of a Ph.D. study programme.
Knowledge:
The student will get an overview a range of statistical concepts and tools:
- Regression
- ANOVA
- Interaction between factors
- Design considerations
- Model check and fit, data representation
- Systematic and random effects
- Logistic regression
- Contingency tables
- Use of statistical software (SAS)
Skills:
A student that has successfully finished the course will possess the following qualifications:
- be able to select the appropriate statistical model for the design in question.
- be able to apply General Linear Models (analysis of variance (ANOVA), analysis of covariance (ancova), polynomial and multiple regression, nested and mixed anovas)
- be able to describe multivariate anova (manova), repeated measurements anova, logistic regression and log-linear models.
- be able to develop and apply statistical models that incorporate qualitative (both fixed and random effects) and quantitative variables, main effects, interactions, and second or higher order terms.
- be able to use statistical software (currently SAS) to load a data set, to sort and summarize data, to perform relevant statistical analyses, and to report the results either graphically or in tables.
- be able to estimate the parameters of a statistical model and their standard errors, and to test whether they are significantly different from 0.
- be able to identify significant and non-significant factors so as to simplify the statistical model using various criteria for best fit.
- be able to apply a priori and a posteriori tests to identify treatment differences.
- be able to use the statistical model as a predictive tool to forecast the expected outcome of an observation from a set of independent variables.
- be able to check whether data meet the assumptions of the model and, if needed, to select an appropriate data transformation.
Competences:
The student will learn the most commonly used experimental designs and appreciate their advantages with respect to the subsequent statistical analysis of data. The student will be able to select or, if necessary, to develop a statistical model for the experimental design, state the relevant statistical hypotheses, conduct the statistical analysis (generally using statistical software), present the results in a clear and understandable way, and finally interpret the results in a biological context to reach a sound conclusion based on the empirical evidence. In addition, the student should possess the necessary theoretical insight in statistics to be able to understand and comment critically on the use of statistics by others.

- Credit
- 7,5 ECTS
- Type of assessment
- Continuous assessmentDuring the course the student has to give a short (10-15 minutes) individual presentation of a case study that has involved statistical analysis. The study may either be taken from literature or be his/her own project.
In order to pass, the student should have participated actively in the course by being present at both the lectures and the exercises (max 20% absence from lectures and exercises).
Furthermore, the students should in groups of 2 or 3 hand in three homework exercises of an acceptable standard. - Marking scale
- passed/not passed
- Censorship form
- No external censorship
One internal examiner
- Re-exam
Renewed hand over of three homework exercises and an individual oral presentation of 10-15 minutes duration.
