We attempted to make mark awarding and statistical analysis of student grades attended the Board Examinaton 1983 by the application of the microcomputor—TRS-80

Model Ⅲ(48K)with self-made program numbered 47.533 K(bytes)in analysing the results among 2 departments

12 classes

407 students

16 subjects and total 200 questions. There are 12 tables in accordance with 12 categories investigated together with the entery-error correction measures. The items are listed as follows: the grades of students in different departments

classes and the average

standard deviation and the T values; the correct answering rates among departmentsⅠandⅡ

and the differential index(r); the correct answering rates and U test values in departmentsⅠandⅡ

and the order-list of different subjects arranged according to U values; the frequency distribution chart of students grades and the normal test(D); the coefficicnt of reliability(R)and the order-list of classes arranged according to the T value; average correct answering rates and U value among different types of questions; analysis of questions

differenciating into satisfactory

dfficult

easy and not satisfactory 4 categories; order-list arranged according to the % of fine questions made by different systems; order-list of students arranged according to grades awarded. The trial scheme of the application of microcomputor including the self-made programs proved to be effective and accurate

otherwise the work could not be completed within such a limited time.However

since the entery error existed somewhat greater than 1%

that we suggest to install a photo-electric scanning apparatus in order to prevent the input error thus to ensure its accuracy.
