Research On Statistical Analysis Of Educational Testing Data Under Open Source Environment

In large-scale education tests,the test data statistical analysis may provide the science, the reasonable basis for the education decision-making. Realizes under the opening sound code's environment using the science computation software to the test data carries on the statistical analysis computation,not only may reduce the cost,moreover can obtain calculates the platform reliably.This article to uses the test data statistical analysis the basic principle, to the large-scale test's data from the Data organization, the data description, the score comparison as well as the examination paper difficulty, the letter, the validity and area indexing several aspects has carried on the statistical analysis.In the test data quantity very huge situation, has built the parallel computing platform, used the divide-and-conquer strategy to design the test data statistical analysis computation parallel algorithm, and in opened the source under the environment to program realizes. Obtained the quite good results.
