This study session introduces some of the discrete and continuous probability dis?tributions most commonly used to describe the behavior of random variables. Probability theory and calculations are widely used in finance, for example, in the field of investment and project valuation and in financial risk management.
Furthermore, this session explains how to estimate different parameters (e.g., mean and standard deviation) of a population if only a sample, rather than the whole population, can be observed. Hypothesis testing is a closely related topic. This session presents techniques that are used to accept or reject an assumed hypothesis (null hypothesis) about various parameters of a population.
The final reading introduces the fundamentals of technical analysis and illustrates how it is used to analyze securities and securities markets. Technical analysis is an investment approach that often makes use of quantitative methods.
