The teaching is organized as follows:

Learning outcomes

The course of Statistic Methods for the Social Sciences, proposes at first him to familiarize the students with the fundamental methodologies of the scientific search, gradually bringing them to the discovery of the connected problem list to the construction of the statistic information. Statistic methodologies will be drawn by the analysis of the necessities of synthesis and descriptive required by the data presents in the statistic collective. Potentiality and limits of the same will broadly be characterized. Some varying ones of demografic nature, even if not suitable expressly in the program they will serve as I support operational of the development of some methodologies.
Subsequently the important theme of the statistic inference is faced, deepening the competence already matured by the student in a circle fidescrittivo and allowing to gather more tightly him some application aspects of the subject. The student will enter the world of the probability in gradual way and progressively sharpening the knowledges pregresse. To face all these thematic rather complex, is only used besides the tools of elementary mathematical analysis, skipping limits, derived, integral etc that they overcome the least program of the senior high schools. Some concepts can be only intuitions, for others verifications will be developed to hoc, but in the big part of the cases the results gotten at the end of this teaching are substantially equivalent to those of a fundamental course of statistic.

To latere it is anticipated the special course of Laboratory of statistic Methods for the social sciences that it will allow him to directly verify the validity of all the methodologies and the models introduced to lesson besides allowing the student to deepen potentiality of a diffused spreadsheet.

Program

- Introductory general concepts: concept of Statistic, general definitions, the statistic surveys.
- Staircases of measure.
- The phases of the search: preliminary phase, of planning, the questionnaire.
- Survey: harvest, classification and tab of the data. Problem of the grouping of the data in classes; meaning of the frequencies and operatività of the same.
- Graphic representations.
- Averages of position. Fashion, Median and quartini.
- Elaboration of the data: the arithmetic average and his/her ownerships, the geometric average, the harmonic average. Relationships of composition, of derivation, of duration.
- The variability and his/her measure: I discard interquartile, varianza, middle quadratic discard, absolute middle discard and ownership of such measures.
- R of the gini
- Charts to double entrance and multiple entrance. Sign to the independence in such case.
- Cloud of points - Regression, non linear (sign) regression.
- Interpolating straight line - Coefficient of linear correlation and his/her meaning
- Parameters of the interpolating straight line gotten with the so-called one "method of the moments"
- Causal champion, tables of aleatory numbers, errors of survey in the investigations campionarie.
- Signs of calculation of the probabilities
- The probability according to the different theories
- Signs on some discreet causal variables: ipergeometrica, discreet uniform, Poisson.
- Some notable distributions: the normal distribution, the binomial distribution, the distribution the average's campionaria.
- Punctual respects.
- Degree of trust of the respects: concepts on the statistic inference, the appraisers' ownership, the punctual respect in the case of sampling bernoulliano, distribution of the middle campionaries
- The respect to alternate: interval of confidence for an average, for a frequency.
- The dimension of the champion.
- Verification of hypothesis in the case of a champion.
- The measure of the relationships of dependence in the case of two considered variables jointly: definition of statistic independence.

Examination Methods

Is obligatory the initial written check. Founding on the result of such test (that can also be replaced by checks in itinere in accord between the Teacher and the students) the oral one (not necessary if the vote is already positive) will subsequently be developed.
