Curriculum organisation and delivery
The course will be taught across a whole academic year using lectures and practical classes involving computers. It will start from an elementary level and develop quickly to advanced statistics based on the general linear model used in analysis of variance. Students will carry out a personal experimental project that will be discussed in class and in individual supervision.
