Objectives

The aim is to enable students to carry out statistical analysis, interpretation and publishing results. For this, students are expected to distinguish the measurement scales and interpret the different types of measurement errors, to estimate statistical parameters, to perform hypothesis tests by parametric and non-parametric methods for one and two populations.

Learning outcomes and competences

As learning outcomes students are expected to gain analytical and critical capacity from the statistical results of analyzes carried out or resulting from published articles.

Eligibility for exams

The TP and P classes are subject to the faults. To obtain frequency students will have less than 1 / 4 faults in relation to the number of classes taught in the school year or result in the previous academic year.

Calculation formula of final grade

Normal Season: The evaluation system consists of the procedural method of assessment, summative and discontinuous, spread over three times: 1^st Moment of assessment - theoretical test (T1) of Biostatistic principles (quote 0,45); 2^nd Moment - Practical exam (P2) of statistical analysis in SPSS and calculation (quote 0,45); 3rd Moment - Attendance (quotation stratified in relation to attendance. In addition to the mandatory minimum and a maximum of two values (quote 0,10). The approval is made to depend on a minimum grade of 10 marks at any moment of evaluation described. Formula assessment procedure, discontinuous and summative: final assessment = 0,45*T1 + 0,45*P2 + attendance. Students often failed in the previous year, but did not have the attendance component. The approval will be according to the formula of final evaluation = P1*0.5 + 0.5 * T2, depending on a minimum score of 10 in two evaluation described P1 and T1. Appeal chance: will be submitted to the examination appeals students without prior approval and which have no more than 25% of faults in relation to the lessons given (taking frequency arising out of or in previous years). This method of evaluation consists of an examination - a practical exam (P) and theoretical exam (T) not subject to minimum grade. Students who pass the exam (T) in regular season are exempt from taking the same exam (T) of appeal season. Formula assessment for final exam: assessment Final Exam = 0,5*P + 0,5*T.

Special assessment (TE, DA, ...)

Special season exam = 0,5*P + 0,5*T
