Reaction time that is the period between the emerging of the target stimulus and the subject's motor response is an important and informative tool in the study of cognitive ability in psychology and other disciplines. In this study we proposed to evaluate attention level of students before and after an exam via a designed stimulus system. The study conducted on 30 individuals that are studying at...
There are many methods in statistical analysis, but the basic approach is quantitative analysis. Statistical analysis requires a combination of quantitative and qualitative analysis. Qualitative analysis is fundamental, and a quantitative analysis, which is the core of statistical analysis, is based on the precision of the qualitative analysis. The process of statistical analysis includes qualitative...
In order to alleviate the increasing contradictions between the service supply of service zone and service demand of service object, and maintain the efficient, comfortable and safe highway, logical extension of Highway service zone is imperative. This paper researches on the service zone of Beijing-Hong Kong-Macao (B-HK-M) Expressway in Guangdong section through qualitative analysis and quantitative...
Expert consultation is a group decision making method often used in the argumentation. This paper proposes a 2-mode network for the expert consultation, and gives a procedure to study the network in static and dynamic way. The procedure includes a series of analytical methods such as correspondence analysis, cluster analysis, multi dimensional scaling, degree analysis and centrality analysis. Case...
In the challenge competition world, “learn how to live together” is possibly one of the major educational issues. Cooperative learning has been honored as “one of the most important and successful teaching reform”. By means of documental data method, survey method, psychological measurement, teaching experiment, statistical method and connecting with basketball teaching, the research had directed...
The new method of one-factor analysis of variance for medical statistical data with binomial distribution is studied in this paper. The total probability variation of the control groups is decomposed into sample probability variation and probability variation between samples in control groups, the statistical analysis will be done to the data with binomial distribution by using one-factor analysis...
As student satisfaction surveys are a primary method of evaluating university faculty teaching performance, it is essential to develop an understanding of the factors driving course evaluation. Here we discuss experiments conducted to investigate the value of various service actions in the classroom environment. In particular, we focus on the offering of excitement needs such as giving candy, humor,...
This paper, taking American new economic history as an example, investigates the base discipline of the application of statistical methods in economic history research, and explores the significance of the application of statistical methods in promoting economic history research.
Urban agriculture in Xi'an has taken shape and has its own characteristics. This paper based on the analysis on the main tectonic plates, industrial belts and their corresponding distribution areas, making an analysis on 6 main target data out of mass of data with the methods of factor analysis and cluster analysis. Based on the researches mentioned above, this paper finally summarized the characteristics...
This paper is based on data analysis and literatures, land use system, demographic factors, and economic development situation, fiscal and financial policies which have influence on the price of the house are studied. In order to discuss housing price purely on the basis of statistical data, the main factors and their weights are calculated based on the survey of house price and usage of grey theory...
Statistics of static loading tests for 5470 prestressed concrete pipe piles in soft soil regions are presented in this paper. The data shows that the pipe piles with a diameter of 400mm and 500mm are widely used, which account for 28.21% and 45.79% of all statistical piles respectively. The recommended design value of the length is in the range of 10–45m and the length-diameter ratio should not exceed...
The safety grade of Long and Steep Downhill Roads (LSDRs) on mountainous expressway is determined on the basis of analysis of safety factors, and the safety evaluation index system and the weights are build. Based on the theory of grey clustering, the classic whitening weight function is improved, and a gray fixed weight-clustering evaluation model of LSDRS is established to evaluate the security...
The paper mixes extension theory and gray clustering method, and constructs the evaluation system of the bus rapid transit system based on gray extension matter-element model, using the evaluation grade of bus rapid transit system, the indicator evaluation standard and the basic characteristics value as the matter elements, applying gray clustering method to calculate the weight and the correlation...
There are many undesirable systematic variations in general microarray experiments. Normalization is the process of removing such variations which affect the measured gene expression levels. The aim of an effective normalization method for cDNA microarray data is to remove noise while retaining the signal in the data. A composite three-stage normalization method was proposed in this paper. The first...
This article carries out an investigation on the travel package arrangement of some tourist agencies in Shaoxing, Suzhou, Wuhan and Kunming from four aspects, and reaches some conclusions about the recognition of the tourism brand of "Zhoushan Islands" based on the statistics and analysis.
Since the late 1990s, studies of team performance management have experienced a great growth over a decade. Researchers study on this field from several different aspects and subjects. Reviewing these years' hot domains and research trends of team performance management, it's clear that the study from the very beginning have a comprehensive, intercrossing and complicated feature. Taking use of co-citation...
Wind power is expected to contribute significantly to the renewable energy targets owing to advancements in wind technologies, falling capital costs, abundance of free resource and commercial viability. However, it also brings into a lot of new challenges for the power network planning and operation. The predictability of wind power in managing load and generation balance is very important. If the...
Internet and database technology provide the conditions for us to learn human behaviors empirically. Exploring these behaviors is important for us to understand internet users' surfing habits, and to set the stage for better research on social dynamics closer to reality. In this paper, we explore the Internet users' post and reply behaviors et al. in an internet forum, Tianya. Statistical analysis...
After a brief analysis to the information spreading mode under internet-based micro-blog platform, it quickly classifies and audits the related mirco-blog content in the spreading process in this paper. Then, by analyzing the sender's mood tendency to some specific topics in the content of micro-blog message, it proposes a content audit model under the micro-blog service platform. Furthermore, by...
The index system was constituted in this paper using meteorological data, vegetation data, soil data and socio-economic statistics, and then eco-environment vulnerability was evaluated. Based on the powerful spatial analysis function of GIS, using 100m×100m real area as basic unit, the eco-environment vulnerability of Baishan Region was evaluated with the Analytical Hierarchy Process and Weighted...
