كثيرة هي الأفكار التي تخطر على البال و كثيرة هي الأسئلة التي تتوارد إلى الذهن عندما يتعلق الأمر بتحليل ظاهرة ما باستخدام أساليب و أدوات تساعد في اتخاذ القرارات المناسبة. حاولنا في هذا البحث عرض أهمية علم الإحصاء و أهم أساليبه بالاعتماد على عدد المتغيرات الخاضعة للتحليل حيث تم استخدام: - المؤشرات الإحصائية الوصفية في حال كان لدينا متغير واحد - الأرقام القياسية في حال كان لدينا متغيران - التحليل العاملي و تحليل التباين في حال كان لدينا عدة متغيرات، و تم تطبيق هذه الأساليب على إنتاج محصول القمح المروي بنوعيه الطري و القاسي خلال الفترة 2000 – 2010 و العوامل المؤثرة في إنتاجه و المتمثلة في: المساحة المزروعة – المردود – الأسمدة– المياه- متوسط التكلفة – متوسط السعر، و من ثم تم تحليل البيانات باستخدام الحزمة الإحصائية SPSS و برنامج Excel ، حيث تم تلخيص البيانات في عاملين رئيسين يفسران معاً 86.116%)) من التباين الكلي، عبر العامل الأول عن الأرض و ما يتعلق بها من خلال مجموعة من المتغيرات هي المساحة المزروعة و ما تحتاجه من أسمدة و مياه، أما العامل الثاني فقد عبر عن أهمية سعر مبيع الكيلو غرام من المحصول.
There are many ideas that come to the mind and many questions that keep coming to the mind when it comes to analyzing the phenomenon of using the methods and tools to help in the planning and making appropriate decisions. In this research we tried to display the importance of statistics and the most important methods depending on the number of variables used in this analysis: descriptive statistical indicators in case we had one variable, indexes in case we had two variables, and factor analysis and analysis of variance in case we had several variables. These methods were applied to production of irrigated wheat crop, both types soft and hard, during the period 2000 - 2010 and the factors affecting its production, such as: the cultivated area, yield, fertilizers, water, the average cost and the average price. Then the data were analyzed using the Statistical package SPSS and program Excel. After that, they summarized in two main factors that justify together (86.116%) of the overall variance. The first factor was related to the land and everything related to it through a set of variables, which are: the cultivated area and the need to fertilizers and water., The second factor was the importance of the selling price of the crop per kilogram.

Foreign direct investment FDI has been started to play a major role in supporting the
growth of the economies of developing countries since the eighties of the last century,
taking advantage of the rapid spread of information and communication tech
nology ICT
and the trend towards a market economy in most developing countries and trade
liberalization in them. These countries began to depend more on foreign direct investment
because of the great benefits that derive from it in terms of capital, employment and
increase in exports, or in terms of obtaining the modern technology which is necessary to
achieve the economic development.
In Syria, foreign direct investment flows started to increase since 2003 as a result of
the new directions of the Syrian government to open up to domestic and foreign private
sector, and reliance on the market economy.
The objective of this research is to shed light on the reality of foreign direct
investment in Syria, and to clarify the impact of this investment on economic growth
during the period 2000-2010. It has reached to find out that this effect was weak.
The study was conducted in the eastern region of Syria to know the extent of
cultivation development of wheat and cotton production and the factors
affecting these crops during 1996-2010. The results showed that the effect of
time on the productio
n and productivity of wheat was not changed statistically,
while the cotton area was decreased significantly during the study period. The
total production of wheat was also affected significantly and positively by
cultivated area and planting costs per hectare, and negatively by purchase
price, while the production of cotton was affected significantly and positively by
costs and purchase prices. According to the geographical region, the results
showed that the production in the eastern region was significantly affected by
Al-Raqqa production for wheat and cotton crops and Al-Hassake production
for wheat crop. However, wheat productivity at Deir Ezzor was significantly
superior compared to Al-Raqqa and Al-Hassake. The study recommended
expanding the cultivation of wheat and cotton and support and expand the role
of agricultural extension.
Wheat is the most cultivated strategic crop in Syria , it occupied first
rank of cultivated area , and second rank of production value , in addition
to that bread is the main nutrition in Syria .
The aim of present study is to recognize to sectori
al structure of
wheat production in Syria through studying the spatial concentration,
specialization, economic efficiency, and recognizing the dynamic
production of wheat during the study period to give a real picture about
this strategic crop .
The practical significance of this study is to give a real picture about
trends of wheat production, areas, yield, and to determine the level of
spatial concentration, specialization, and economic efficiency in every
governorate in Syria during studying period to show the impact of spatial
diversities on wheat production in Syria .
The different types of tax revenues are considered the most important types of public
revenues, particularly in developing countries. Given this, the proportion of tax revenues
make up the biggest amount of public revenues, and this is observed in
the budgets of the
Syrian Arab Republic. The evolution of the size of public revenues, especially tax revenues
compared with the Gross Domestic Product (GDP), shows the state's ability to finance its
growing public expenditure. It also shows the ability of the state in developing countries to
redirect part of cash surpluses to finance investments that help to establish the
infrastructure, and this applies to Syria. Therefore, it is necessary for us to study the
evolution of tax revenues in Syria because of its importance and its role in the economic
development process. This study is based on the cut accounts of the state budget, not on the
expected budgets in order to obtain accurate results from the process of the evolution of
taxation of different types, compared with the GDP in Syria, which is also reflected on
Syria's tax energy and its evolution and impact on tax evasion. This study proves that
economic reforms reflected on the financial policies and their tools in Syria during the study period
show a development in taxes as a result of a decrease in tax evasion and an increase in tax energy.
This study aimed at using Multi-Variables Analysis in classifying household
spending in Syria and identifying which of the social factors considered in the study
influence significantly this classification and which do not.
The most prominent resu
lts were: the possibility of classifying household spending
into three levels (high, medium and low), there is a statistical significance of the factors
(the percentage of urban population to total population, university education and above,
number of married people and those in marriage age ) on the household spending
classification. There is no statistical significance of the factors (educational levels below
university education, non-married people, divorced or being widowed) on the household
spending classification.
