摘要：Data mining has made a great progress in recent year but the problem of missing data or value has remained great challenge for data mining. Missing data or value in a datasets can affect the performance of classifier which leads to difficulty of extracting useful information from datasets Dataset taken for this study is student records of university system that contains some missing values. The missing value are present in tm_10and tm_12. To estimate missing values classification algorithm (C4.5/J48) is used and then accuracy is measured through confusion matrix. Weka data mining tool is used for this analysis.
