## Learning Assessment

### Learning Assessment Procedures

During the oral exam the student will have to demonstrate the aquisition of the main characteristics of geological data and the use of the main methods of graphical and numerical representation as well as the basic concepts of descriptive statistics

### Examples of frequently asked questions and / or exercises

what are the scales in which the data can be divided?

Having a normal frequency distribution how can we calculate the probability?

What is the difference between accuracy and precision of a measurement?
