#### Course Description

The most desirable demand of the people worked in health area is to interpret the situations derived from

the any phases period of sickness and patients symptomatic complaints and expectations related with

recover their health in a short times. The matter likely is about results which will realize at the future or will be realized at the past by the studies whether are prospective or retroprospective.

Statistics presents some successful techniques which are about the problem. One of them is the regression method. In other words, it is the technique that predicts the best fitting values for the actual observations respectively. Regression technique can be modeled according to the problem parameters like expected outcomes and complained symptoms that interact with each other. They are assessed and converted to the regression model. The parameters are appreciated for the numerical or categorical result(s).

Next part of the course is about the subset of the regression analysis which is complementary support based on the situations which involve categorical observations and categorical predictions.

This course will explain to the trainee the regression analysis models are simple, multiple and logistic in order of difficulty. The presentation of the course will provide a simple, smart and summarize statistical explanations for the people employed in health and social disciplines. However the people in other disciplines can utilize the richness of the course.

#### Course Objectives

At the end of course, the trainee will be to:

- Analyse the situation statiscally in parameters,
- Predict the parameters expected,
- Interpret the outcomes of the situations,
- Understand how the parameters likely vary in confidence intervals,
- Design a 2x2 crosstable about the results of case control study surveyed,
- Learn how to extract the statistics subjected from 2x2crosstable,
- Interpret the results of the case control study surveyedm,
- And prepare a statistical report for case control study.

#### Who Should Attend?

- Physicians and Managers who are fighting to solve health and hospital problems involve statistical matters
- Statistical Fresh Researchers studying in case control studies(cohort studies)
- Anyone who wants to learn the statistical procedures to evaluate the comparison of nominal results associated with each other
