Classes are expository and include examples and exercises for applying the acquired knowledge. Analysis of real or simulated data using the statistical software SPSS will be developed in laboratorial classes. Throughout the semester, students may develop and present studies on statistical applications.
During the semester, students can also use tutorial time to discuss their ideas and clarify possible understanding difficulties.
Statistical goal is the study and description of random phenomena by estimating the probability distribution underlying such phenomena. The Descriptive Statistics, which includes the Exploratory Data Analysis, resumes and draws the main conclusions about the recorded data. In the Mathematical Statistics, supported on Probability, inferential methods are developed to evaluate the quality of the statistical conclusions about the general phenomena under study. To better reach these goals, this course is complemented with the analysis of real and simulated data using a statistical package (SPSS).
This course allows developing the following skills: ability to calculate; using computational tools; knowledge of mathematical results; ability to generalize and abstract; design and use of mathematical models for real situations. On a personal level, it allows to develop individual initiative, teamwork, research and independent learning.
