Introduction to Statistical Modeling

(16485)

Students will acquire knowledge and skills necessary to:
1. Define populations for a statistical study
2. Compute point estimators and confidence intervals for population parameters
3. Build Hypothesis about a distribution
4. Test hypothesis about the parameters of the chosen model
5. Evaluate how well does the model fit to reality
6. Understand the limitations of the methods that have been studied and the conditions under which they lead to wrong conclusions
7. Carry out the abovementioned analyses in statistical software
Students will be able to:
1. Develop their ability to think analytically
1. Become familiar with a statistical software
2. Establish a framework to solve problems
3. Develop their interactive skills
4. Enhance their critical thinking
5. Improve their learning skills and communication
