Learning outcomes |
This course aims to enable students with a set of skills/knowledge corresponding to acquisition of the following capabilities 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 Concepts Nature and context of analytical problems. Importance of statistical treatment of experimental results. Experience planning. Review of concepts: expression of concentration. Presentation of statistical tests in Excel 2. Probabilities and Combinatorial Analysis Probability and most common distributions (discrete and continuous): normal, t, chi-square and F. Hypothesis tests: the null and alternative hypothesis, type I and II errors, F and t test (paired and unpaired). 3. Errors Errors 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. Analysis of Variance: ANOVA Comparison of various averages. Analysis of variance: one-way and two-way. Other significance tests: t-test, F-test, outliers and
