Abstract:
The choice of faculty selection in the joint higher education entrance examination does not only depend on the applicants preference. In order to select the faculty which is both preferable and appropriate to the applicants academic ability, other factors needed to be taken into consideration are the applicants academic ability, the total number of applicants and minimum entrance examination score of each faculty. This research constructs a regression model predicting the entrance examination score from the individual subject score of M.S. 4 and M.S. 5 of students of Streevidaya School, Streevidays II School, Taweetapisek school and Samsenvidayalai School. This research also provides a statistical Model which enables the prediction of the total number of applicants and the minimum entrance examination score of each faculty. It can be summarized that the M.S. 4 and M.S. 5 individual subject score of students of of Streevidaya School, Streevidays II School, Taweetapisek school and Samsenvidayalai School display a linear relationship with the entrance examination score. Hence, the entrance examination score can be estimated by using the M.S. 4 and M.S. 5 individual subject score or the total score of related subjects of M.S. 4 and M.S. 5. Besides, score of each subject in the entrance examination can be estimated by corresponding subject score of M.S. 4 and M.S. 5. These estimated scores can be combined to be the estimated entrance examination score. Estimates of the entrance examination score form the above three regression models appear to vary insignificantly in terms of quality. Therefore, selection of a model may depend on the availability of M.S. 4 and M.S. 5 subject score. As for the study of the future trend of the total number of applicants for each faculty, the faculties can be classified into two groups as follows : 1. Faculties which have linear or parabola trend model 2. Faculties which have no linear trend model. The latter group is study by using simple moving average method. In estimating the minimum entrance examination score of each faculty, it is found that the minimum score has no linear relationship with the academic year or time. When comparing the estimate of the minimum score obtained from the simple moving average method and simple mean, it can be summarized that both estimates are equally valuable. However, as simple mean has the benefit of providing estimates in terms of confidence interval, it is recommended that mean of past minimum entrance examination scores be used.
