Course  Definition and Description  ( Brief  Contents ) 

The course aims to demonstrate the role of statistics to reduce the efforts that scientific studies do for reducing data without loss its important information. Include the following concepts: descriptive data (quantitative and qualitative data) - definitions of sample and population in addition to the frequency distribution of statistical data- the elementary of probability theory with maintaining the arithmetic accuracy at the course elementary level, clarifying the random variable concept and the probability distribution and introduce it as an arithmetic model to apply it to real physical problem.
