Learning Objectives
The course aims at providing students with theoretical and practical tools (using Excel) useful to analyse and process data sets of biological nd biotechnological kind.
Program
1. Descriptive Statistics
1.1 Statistical data and their graphical representation: cartesian diagrams, bar graphs, histograms, aerograms (pie charts).
1.2 Absolute, relative, percent and cumulative frequences.
1.3 Centrality (position) indexes: mean, mode and median. Quantiles and quartiles.
1.4 Dispersion (variability) indexes: variance, standard deviation, mean absolute difference, range, variation coefficient, interquartile difference.
1.5 Shape indexes: skewness, kurtosis.
1.6 Interpolation and approximation of experimental data.
1.7 Simple linear regression: the mean squares line; index R^2.
1.8 Pearson's linear correlation coefficient.
1.9 Regression and correlation; residual analysis.
1.10 Applications with Excel
2. Probability Theory
2.1 Events and definitions of probability of an event: classical, frequentistic and axiomatic definition by Kolmogorov.
2.2 Disjoint and independent events. Conditional probability.
2.3 Theorem of the sum and of the product; total probability theorem; Bayes' theorem.
2.4 Diagnostic tests. Sensibility, specificity and predictive value of a test.
2.5 Hints of combinatorics: permutations, combinations and dispositions.
2.6 Random variables (r.vs.): discrete and (absolutely) continuous r.vs; cumulative distribution function, distribution or density function of a r.v.
2.7 Centrality and variability indexes for r.vs.
2.8 Probability distribution functions of (discrete) r.vs: Bernoulli, binomial, Poisson r.vs.
2.9 Probability density functions of (coninuous) r.vs: exponential and Gausian r.vs. Use of the tables of the standard Gaussian r.v.
2.10 Central Limit Theorem and corollaries.
2.11 Applications with Excel.
3. Basic Inferential Statistics
3.1 Deductive and inductive inference; direct and inverse inference.
3.2 Population and sample. Distribution of the sample mean.
3.3 Hints of estimation theory and hypotheses testing (Neyman-Pearson and significance theories).
Bridging Courses
Although not compulsory, having passed the exam of Mathematics (first year, 8 CFU)) is highly recommended, especially for the comprehension of Section 2, "Probability Theory".
Learning Achievements (Dublin Descriptors)
Students will have to show:
D1. A detailed knowledge and not mnemonic comprehension of the treated subjects
D2. The ability of applying the known statistical methods to different and new contexts
D3. The capability of using simple computational tools (Excel) for statistical data visualisation and processing
D4. The ability of interpreting the achieved experimental results on the basis of the used statistical methods
D5. The use of specific scientific language while exposing the treated subjects.

M. Abate, Matematica e Statistica (3rd edition, or preceeding) - Le basi delle scienze della vita, McGraw-Hill, 2017 or any equivalent textbook in English.
- Assessment
Oral examination on the entire program, and laboratory test on the use of Excel.
- Disabilità e DSA
Le studentesse e gli studenti che hanno registrato la certificazione di disabilità o la certificazione di DSA presso l'Ufficio Inclusione e diritto allo studio, possono chiedere di utilizzare le mappe concettuali (per parole chiave) durante la prova di esame.
A tal fine, è necessario inviare le mappe, due settimane prima dell’appello di esame, alla o al docente del corso, che ne verificherà la coerenza con le indicazioni delle linee guida di ateneo e potrà chiederne la modifica.
