Objectives and Contextualisation

The objective of this course is to introduce the basic statistical tools to analyze data arising from experiments or observations, focusing on their correct use and the interpretation of the results.

The practices with computer of this subject, that are realized with a statistical software package in the computer classroom, are an indispensable part of the course in order to achieve these goals.

Content

1. Descriptive statistics:

  • Empirical experimet associated to a data frame.
  • Frequency tables and graphs: histograms and others.
  • Measures of localization. Scattering measures
  • Correlation coefficient and regression line.
  • Joint, marginal and conditional data distributions.


2. Introduction to the theory of probability:

  • Basic properties of probability. Combinatorics.
  • Conditional probability and independence. Bayes Formula.
  • Random variables. Density and distribution functions.
  • Expected value and variance. Moments of a random variable.
  • Discrete distributions: Bernoulli, Binomial, Poisson and others
  • Continuous distributions: uniform, exponential, normal and others.
  • Central limit theorem and laws of large numbers.


3. Random vectors and stochastic processes:

  • Joint, marginal and conditional distributions.
  • Bivariate normal distribution. Covariance and correlation coefficient.
  • Functions of random variables: distributions khi-square, Rayleigh, Rice.
  • Concept of stochastic process. Poisson processes. Markov chains.


4. Statistical Inference:

  • Estimation and confidence intervals of averages, variances and proportions.
  • Tests for the expected value and for the proportion.
  • Comparison tests for expected values and proportions.
  • Khi-square tests: goodness of fit, independence and homogeneity.

Methodology

The course consists of:

   1. Theory classes where the basic concepts of the subject are introduced and the main techniques of statistics are explained, showing examples of their application.
   2. Problem solving classes where the concepts and statistical tools introduced in the theory classes are put into practice by means of the analysis of concrete examples.
   3. Practices at the computer classroom where the student will learn to use specific statistical software.

•Study and personal work weekly guides (GETPS), as well as other materials, will be published in the course workspace on the UAB Virtual Campus Moodle.

Annotation: Within the schedule set by the centre or degree programme, 15 minutes of one class will be reserved for students to evaluate their lecturers and their courses or modules through questionnaires.

Assessment

The mark of the subject by continuous assessment, AC, will be obtained from:

  1. the marks of two partial exams, E1 and E2, (0<= E1, E2 <=10).
  2. the mark of the practice exam with computer, P, (0<= P <=10).
  3. delivery of resolved problems and exercises, Pb, (0<= Pb <=10).

according to the formula: AC = 0,25 E1 + 0,30 E2 + 0,25 P + 0,20 Pb.


The student passes the course if AC is greater than or equal to 5 and min(E1,E2)>=3. Otherwise has a recovery exam whose mark, ER, will replace the mark of the two partial examinations, E1 + E2, and even the mark of the delivery of solved problems, Pb, whenever it is most favorable. However the mark P of the practice exam is NOT recoverable. In the first case the final mark F will be given by the formula F = 0.55 ER + 0.20 Pb + 0.25 P, and by F = 0.75 ER + 0.25 P in the second case. Notice now that in order to be able to attend the recovery exam, the student must have previously been evaluated of continuous assessment activities with a total weight superior to 65%.

It is considered that the student presents himself for the evaluation of the course if he has participated in evaluation activities that exceed 50% of the total.
