This curricular unit (CU) aims to provide the theoretical-practical knowledge of statistical methods focused on studies in Management, aided by statistical software.
Descriptive Statistics Inferential Statistics Correlation and Regression Multivariate Statistics
It is hoped that upon completion of this course unit the student will be able to:
1 - Select the descriptive and graphic measures and perform an analysis of a set of data, interpreting in the context of the study;
2 - Formulate statistical hypotheses, identify sampling methods and statistical inference, namely, Confidence Intervals, hypothesis tests;
3 - Study relationships of interdependence using correlation and regression models;
4 - Know and know how to apply other multivariate techniques and, having acquired this knowledge, be able to identify the most appropriate methods for concrete objectives.
5 - use the SPSS statistical software (or another equivalent) on a database, select the analyses, interpret the results and indicate the limitations.-

E-learning
Evaluation is made on individual basis and it involves the coexistence of two modes: continuous assessment (60%) and final evaluation (40%). Further information is detailed in the Learning Contract of the course unit.
Additional study materials will be available on the e-learning platform.
