Abstract— It is developed in ASP.net with C# language. It is Web-enabled, User-Friendly, Interactive, password Protected, menu-driven Package. It provides online data handling, data upload/entry, scrutiny, editing and imputation for missing values. It would be able to analyze survey, data anywhere; results will be made available quickly on the browser itself. It estimates the population parameters based on the sampling data collected using the sampling designs like simple, random sampling – with or without replacement, systematic and probability proportional to size (PPS), stratified sampling, cluster sampling etc. Actually software related to agriculture survey are already available but they are costly, requires extensive coding and domain expertise, stand-alone application, need to install on every machines to work. You will develop web enabled software for survey data analysis, to test and validate the software with real survey data using some advanced techniques. We will also use different type of estimator as median, mean, variance. This project will have good efficiency and consume less amount of time. System can be use for the large survey data having a large no of records of surveys done for different parameters.

Keywords— Asp.net, Data analysis, Data imputation, Data management, Mean, Mean of neighboring unit, Zero

I.Introduction

Almost as long as there have been many survey in different fields but most of the time they are not processed online. Here this project helps us for generate population parameter for each crop in agriculture field by using different online sampling techniques. Online agriculture sampling has a module for imputation of missing values using mean, zero and mean of neighboring units methods. It has a user friendly, data management module for importing data from commonly used data file formats and usual editing options. It has a data management module for importing data from commonly used data file formats (.xls and .txt) and usual editing options. It is based on the client-server architecture, requires only an internet browser to run. It needs to install or deploy on one machine (web server).

  1. THEORY

 

II.Sampling Methods Used in online agriculture sampling

If you survey every person or a whole set of units in a population you are taking a census. However, this method is often impracticable; as it’s often very costly in terms of time and money. For example, a survey that asks complicated questions may need to use trained interviewers to ensure questions are understood. This may be too expensive if every person in the population is to be included. Sometimes taking a census can be impossible. For example, a car manufacturer might want to test the strength of cars being produced. Obviously, each car could not be crash tested to determine its strength.

To overcome these problems, samples are taken from populations, and estimates made about the total population based on information derived from the sample. A sample must be large enough to give a good representation of the population, but small enough to be manageable. In this section the two major types of sampling, random and non-random, will be examined.

Random Sampling

In random sampling, all items have some chance of selection that can be calculated. Five common random sampling techniques are:

  1. SIMPLE RANDOM SAMPLING
  2. STRATIFIED SAMPLING
  3. CLUSTER SAMPLING
  4. MULTI-STAGE SAMPLING

 1.Simple Random Sampling (SRS)

A sampling procedure that assures that each element in the population has an equal chance of being selected is referred to as simple random sampling.

In small populations such sampling is typically done “without replacement”, Although simple random sampling can be conducted with replacement instead, this is less common and would normally be described more fully as simple random sampling with replacement.

  1. Stratified Sampling

A general problem with random sampling is that you could, by chance, miss out a particular group in the sample

  1. Cluster Sampling

It is sometimes expensive to spread your sample across the population as a whole.

  1. Multi- Stage Sampling

Multistage sampling involves, combining various probability  techniques in the most efficient and effective manner possible. The process of estimation is carried out stage by stage, using the most appropriate methods of estimation at each stage.The Software being developed lies in the category of web Application. The Three Tier Architecture used is:

III.LITERATURE REVIEW

Survey is the alternative to census: organization of a well-targeted. Agriculture: To obtain a good picture of yield, yearly variations, variations on a Longer time scale, etc  .[1]

Most of the statistical packages available worldwide have more extensive features but they are not of much use for survey statistician because of one reason or another.

Some software already available for survey data analysis are PC CARP, CENVAR, CLUSTERS, SUDAAN, STATA, R and SAS etc. which are applicable on personal computers. Most of these packages have more extensive features than only estimation for complex sample survey data, incorporating software for processing and managing survey data as well. Among the already available software which has extensive features are found to be very costly such as SUDAAN, STATA and WesVar. Few other DOS based software are PC CARP, CENVAR, CLUSTERS, etc. which has now become obsolete. Therefore, indigenous web -based software for the survey data analysis is needed to be developed enabling the analysis process to be easier and quicker.

  1. OBJECTIVE AND PROBLEM STATEMENT                                                                                             Statistical computing is a tool in the hand of agricultural research workers. While they understand the use of statistics and computers, they cannot be expected to take on the role of statisticians and computer professionals. If one can integrate statistics with computers and provide them with a means of processing their data, they can achieve their objectives with

VII. RESULTS

  1. CONCLUSION

Online  Agriculture   sampling   is   designed  to   automate the functionality of the analysis process of the various survey data that  has  been   done   on   various   states  and   districts   and villeges.etc

  1. The main advantage of Online agriculture sampling is that, user can operate a single survey data for more than one estimator at a time.
  2. ONLINE AGRICULTURE SAMPLING is fast, accurate and efficient software that provide satisfaction to its users.
    1. ONLINE AGRICULTURE SAMPLING can import /export data files from different data sources. Like (MS excess, excel, text file).

     

    1. All the generated reports after the analysis can be saved for future use in any format.

     

    1. The researcher will get a better and more standardized product so he will be able to get the results in significantly less time. It will facilitate the use of developed software to real survey data available in the y.
