Research On Spatial Sampling And Statistical Inference Of Social Survey

Based on the community and population data of Wuhan city and the result of the social survey data as the data source,from four aspects:the spatial sampling,evaluation of sampling,improvement of sampling frame and the results of the survey,we systematically study in sampling,the judgment on the rationality of sampling,the method of improving sampling frame,and using the social survey results for statistical inference to improve sampling scheme.The application of the method of spatial balance evaluation and statistical inference to the front of the social survey:sampling,the improvement of sampling frame,and statistical inference of social survey's results,which is after the social survey,is used to evaluate the sampling plan and give amendments,study the optimal sampling plan method.In this paper,the main research work is as follows:(1)Spatial sampling of social survey and correlation analysisFrom the Angle of spatial humanities sociology,we determine the spatial partition standard of spatial sampling for social investigation,put forward the method using random sampling and stratified sampling with the combination of multi-stage spatial sampling.On the basis of this,we make exploration to the sampling result and the attribute data spatial visualization method using GIS technology.Contrast to the traditional sampling result evaluation method,we use the method of nearest neighbor index method,G function method,F function method and Ripley's K function method to evaluate the balance of the spatial sampling's results,comparing the results of different methods,we finally choose the most suitable method for the spatial balance evaluation of social survey.In view of the disadvantage of social survey sampling,extracting the sample from fixed locations to get the sampling plan,in order to be able to effectively evade the issue,we use the enumeration experimental method,select sample set of two different characteristics of distribution equilibrium and accumulation of sample plot to make experiment.In the balance of the sample spatial distribution under the condition of uniform and sampling cost,discussing the improving method of the sampling frame..(2)Software about spatial sampling of social surveyTo develop a software which services the spatial sampling of social survey.It contains inline sampling frame of multistage sampling,the sampling method to judge the results using the nearest distance,to get sampling scheme whose spatial distribution is uniform or most tend to be uniform,and realize the real-time visualization of the results of sampling.(3)The statistical inference study of sampling resultsAccording to the 2014 social survey data of "comprehensive investigation of Wuhan city",using the sample of 2000 degree of job satisfaction,evaluation of the living environment in Wuhan,the happiness of life evaluation data,we infer the thought of Wuhan residents of the overall situation on these three indicators.To compare the result with prior knowledge,according to the existing problems of numerical expression analysis results in different areas,we reverse reasoning sampling plan whether stand or fall,and according to the performance of the regional data,improvement opinions are put forward on the sampling plan.
