Advanced Applied Statistics

Advanced Applied Statistics

It is applied course in statistics that is designed to provide you with the concepts and methods of statistical analysis for decision making under uncertainties. This course is a combination of lectures and computer-based practice, joining theory firmly with practice. It introduces techniques for summarizing and presenting data, estimation, confidence intervals, hypothesis testing, modeling relationships and some multivariate techniques. The lectures focuses more on understanding of key concepts and statistical thinking, and less on formulas and calculations, which can now be done on statistical software.

Categorical Data Analysis

Categorical Data Analysis

The main ideas of the course are to develop a critical approach to the analysis of categorical data often encountered in health sciences research. This process will include gaining some technical insight (mechanics of the statistical methodology behind the ideas) as well as applications of these methods in health-related data. 

Categorical Data Analysis

The main ideas of the course are to develop a critical approach to the analysis of categorical data often encountered in health sciences research. This process will include gaining some technical insight (mechanics of the statistical methodology behind the ideas) as well as applications of these methods in health-related data. Some of the main objectives of this course are:

Statistics for Managers

Business Statistics

Statistics is a field study concerned with gathering, transforming and analyzing data for the purpose of making intelligent statements and drawing appropriate decisions. This course has been designed for Business students so that they can apply their knowledge of Statistics in many practical situations. The purpose of this course is to provide you with a strong background in statistical principles. Our emphasis will be on learning how to be an intelligent “consumer” of statistics, rather than on how to become a statistician.
