Course Objective

The aim of the course is to introduce modern data analysis tools to oceanographers via oceanographic data. All branches of oceanography (physical, chemical, geological and biological) use data sets in research. These are as different in character as are the disciplinary sources of the oceanographers. The statistical theory underlying these basic and widely employed data analysis tools is covered conceptually and also explained by using students' own data sets and personal computer statistical packages.

Learning Outcomes of the Course Unit

1   Recognize the great diversity of oceanographic data.
2   Recognize the need for sampling design and statistical analysis in oceanographic investigations.
3   Demonstrate an ability to formulate statistical hypotheses and design basic experiments.
4   Be able to collect raw oceanographic data and make them ready for statistical analysis.
5   Compute all basic statistics to describe and summarize the collected data and prepare various graphics visualizing the information contained by the data.
6   Apply basic univariate statistical analysis methods to make inferences about the collected data and draw meaningful and valid conclusions.
7   Become able to use certain statistical software (R Project for Statistical Computing) to organize, input and analyse data, and interpret results.
8   Demonstrate critical thinking skills by evaluating the strengths and weaknesses of their own research work and/or that of other researchers from a statistical point of view.

Planned Learning Activities and Teaching Methods

1. Lectures
Class lectures are carried out in a highly interactive format. The instructor prompts students for response to questions posed and solicits their thoughts on issues discussed. Lectures will focus on the transfer of basic statistical concepts and techniques rather than rigorous mathematics. The emphasis will be put on the real world applications, and additional elaboration and illustration will be provided for better comprehension.

2. Class Discussions
In-class assignments and homework assignments are the basis of problems to be solved in classroom discussions. Individual participation by students in classroom discussions will be strongly encouraged.

3. Computer Applications
In the laboratory component, the R - free software environment for statistical computing and graphics (R Project for Statistical Computing) will be introduced to perform analyses of data and to produce graphics.

4. Calculator:
Students will need a scientific calculator (preferably one that can perform basic statistical functions for both one and two variable analyses) for various calculation problems in and out of class, and during exams.

Course Policies and Rules

1. Regular attendance is essential for satisfactory completion of this course. Statistics is a cumulative subject and each lesson day builds on the previous lessons' material. If you have excessive absences, you cannot develop to your fullest potential in the course.
2. The student is responsible for all homework assignments, changes in assignments or other verbal information given in the class, whether in attendance or not.
3. Homework assignments must be delivered at the beginning of the lesson on the date they are due.
4. Students are required to have their own calculator for this course.
