Course Description
Statistical analysis is broken down into five discrete steps of; a) describing the nature of the data to be analysed, b) exploring the relationship between the selected data and the underlying population, c) creating a model in order to summarize the understanding of how the data relates to the underlying population, d) proving (or disprove) the validity of the model and the last step e) employing predictive analytics to run scenarios that will help guide future actions. Handling all these five steps which every person might experience it in different fields such as economics, social science, management, political science and etc. might be cumbersome without using a power full statistical package.
STATA is one of the powerful statistical software which is commonly used in many disciplines. It is a known as a general-purpose statistical software package created in 1985 by StataCorp. STATA's capabilities include data management, statistical analysis, graphics, simulations, regression analysis (linear and multiple), and custom programming.
This course will show how to program and employ the powerful statistical commands available in STATA package by recalling some statistical concepts. The course include but not limited to , introducing STATA windows environment. It discusses how to create a dataset, importing data from other sources, data manipulations, descriptive statistics and regression analysis. It will assist trainees in developing the data analysis skills necessary for autonomous and efficient computer processing, manipulation, and analysis of empirical data various fields such as social science and business.
