Exam Results Fit to a Normal Distribution

Suresh Akella;P.M Diaz, B Suresh Babu


Students of many engineering colleges in Telangana are affiliated to universities. Examination branch collects data of internal evaluation and university external exam, and finally these two results are added to determine the semester academic evaluation and to know the grade of position in the academic credits rating. In this paper, these three steps of results are fit to normal distribution. Further, transformation to standard normal are done. The advantages of obtaining future predictions of performance of this batch are possible and remedial classes or improvement plans for estimated students can be planned. This distribution can also be used for normalizing difficult exams to improve the results and see changes in the distribution. Simulation is done with excel calculations.
