# Data Processing and Analysis

 Code 8631 Year 2 Semester S1 ECTS Credits 6 Workload T(30H)/TP(30H) Scientific area Industrial Chemistry Entry requirements Students need to have previous basic knowledge of mathematics required to realize calculus, understand the concept of mathematical function and variables under the scope of statistical and probability calculations. Mode of delivery Presencial teaching (with frequency of theoretical and practical lessons) -- Work placements Not applicable Learning outcomes This course aims to enable students with a set of skills/knowledge corresponding to acquisition of the followingcapabilities to:analyze, evaluate and present experimental results in statistical terms;identify, quantify and minimize origins and sources of error in chemistry;demonstrate the ability to intervene in the procedures for measurement and quantification commonly used inlaboratories in order to increase their reliability;demonstrate the ability to interpret and compare experimental results obtained in various contexts, before and after being subjected to statistical analysis;within the analyzes of probabilities be able to calculate the possibility to obtain certain results and experimental measurements using previous measurement or results;plan, deliver and treat the results of analytical determinations based on calibration curves or by standard addition method. Syllabus 1. Application of statistics to chemistry. Introduction and Review of ConceptsNature and context of analytical problems. Importance of statistical treatment of experimental results.Experience planning.Revision of concepts: expression of concentration.Presentation of statistical tests in Excel2. Probabilities and Combinatorial AnalysisProbability and most common distributions (discrete and continuous): normal, t, Chi-Square and F.Hypothesis tests: null and alternative hypothesis, type I and II errors, F and t test (paired and unpaired).3. ErrorsErrors in analytical chemistry (origins and consequences).Types of errors (random and systematic).Mean and standard deviation.Distribution of errors.Presentation of results and confidence intervals.Propagation of random and systematic errors.4. Variance Analysis: ANOVAComparison of multiple means.Analysis of variance: one-way and two way. Other significance tests: t-test, F-test, aberrant points and chi-square test. Main Bibliography 1.

MillerStatistical for analytical chemistryEllis Horwood and Prentice Hall1984 Teaching Methodologies and Assessment Criteria Considering that laboratory and practical classes of the industrial chemistry (course) are heavily included in otherclasses, here we intend that students acquired the knowledge and the skills required to improve and implement thestatistical analysis of experimental data and quantifications performed. Beside the theoretical support from classes weimplement several opportunities for the use of the taught issues in the context of laboratory activities, analysis andcontrol of quality, methods and results validation for research and development activities. These last issues areachieved through theoretical practical classes, which include several examples and exercises. Language Portuguese. Tutorial support is available in English.
