### Quick Launch

Advanced Statistic and Computer (557) QUA

Description:

The syllabuses at which this subject is aimed include selected aspects of statistical theory mainly concerning applications in significance testing, sampling and the determination of confidence limits. Before these applications can be studied in detail some preliminary knowledge is required regarding particular statistical concepts such as means, variance and standard deviation and of the general nature and characteristics of frequency distribution.In addition some knowledge is required of the characteristics, properties, and relationships of particular distributions namely the Normal, Binomial and Poisson Distributions.

Statistical analysis or, simply Statistics deals with quantitative data. Statistical Analysis is a scientific method of analyzing masses of numerical data so as to summarize the essential features and relationships of the data in order to generalize from the analysis to determine patterns of behavior, particular outcomes or future tendencies. Statistics can be applied in any field in which there is extensive numerical data, not only in accounting and business, but in medicine, engineering, the sciences, public administration and many other area.

Statistical theory is based on the mathematics of probability which provides the basis for determining not only the general characteristics of data, but also the reliability of each generalization. From a business viewpoint the basic steps in statistical analysis include:

Collecting the data from records or other sources or from sample surveys.

Analyzing and interpreting the figures by means of statistical techniques.

Using the calculated results together with probabilities, costs and revenues to make more rational decisions.
