SSDA – A windows based software for survey data analysis

Analysis of survey data requires the use of specialized software that incorporates most of the available survey designs. Although, a large number of software are available for the analysis of survey data with extensive features and provide good estimation, but at the same time they have been found to be costly, requires extensive coding and domain expertise to get the results. Therefore, a low cost, less complex and user friendly windows based software has been developed for the analysis of survey data. In this paper, Software for Survey Data Analysis (SSDA) has been described. SSDA provides the estimates of population mean and variance for data collected using stratified multistage sampling design and the descriptive statistics. SSDA has modules for data management, analysis, reporting and HTML help. C# (C-Sharp) programming language available under.NET programming environment has been used for developing SSDA. It is anticipated that people involved in teaching sampling methodology, statisticians and agricultural research workers will be immensely benefited by the use of this software.
