Statistics

General

Course Contents

  • Statistical approach to problems: a brief overview.
  • Enumeration (multiplicative principle, enumeration of arrangements, permutations and combinations).
  • The concept and basic properties of probability.
  • Bound probability (definition, multiplicative formula, total probability theorem, Bayes formula), independence.
  • Random variables (distribution function of a random variable, discrete and continuous random variables, probability function of a discrete random variable, density function of a continuous random variable, mean and variance of a discrete and continuous random variable).
  • Special discrete distributions (Bernoulli, Binomial, Poisson).
  • Special continuous distributions (Normal).
  • Central limit theorem.
  • From probability to statistics.
  • Descriptive statistics (frequency distribution table, numerical descriptive measures, bar chart, pie chart, histogram, histogram).
  • Sampling distributions.
  • Estimator (point estimate, properties of estimators, estimate with confidence interval (a) for the mean of a population (b) for the difference of the means of two populations with independent samples and with paired observations (c) for the proportion of a (binomial) population d) for the difference of two percentages).
  • Statistical tests ((a) for the mean of a population (b) for the comparison of the means of two populations with independent samples and with paired observations (c) for the proportion of a (binomial) population and (d) for the comparison of two proportions).
  • Analysis of variance ((a) one-factor (b) two-factor with and without interaction).
  • X2 test (goodness of fit, independence).

Educational Goals

Upon successful completion of the course, the student is expected to:

  • Distinguish stochastic from causal phenomena and experiments.
  • Use basic probability tools and basic enumeration rules and methods.
  • Understand the practical value and importance of probabilities and interpret stochastic phenomena and experiments.
  • Describe and summarize data gathered from observing a phenomenon or performing an experiment.
  • Translate a research question into an appropriate hypothesis test(s), given the data and how they were collected (experimental design or sampling design) and within the limits of the course content.
  • Apply statistical hypothesis tests and construct confidence intervals of his choice to draw conclusions from experimental or sample data (and within the limits of course content).
  • Understand the conditions required for the application of the statistical methods he/shechooses, as well as the necessity of checking these conditions.
  • Understand and correctly interpret statistical significance tests.
  • Formulate conclusions about stochastic phenomena and experiments and interpret them correctly and in terms of the physical problem and not necessarily using statistical terminology.
  • Be aware of the uncertainty (and its size) that is inevitably included in the conclusions concerning stochastic phenomena and experiments.
  • Judge and evaluate conclusions based on experimental or sample data.
  • Select and apply the appropriate methods of statistical inference required to complete a research paper (within the course content).
  • Have the knowledge of the ethical and moral issues related to the collection and use of data and the publication of conclusions drawn from them.
