Table 1: Cont. higher significance of a factor. The research population comprised educationists from the educational domain. Finally, considering the guidelines and requirements of Fuzzy Delphi screening, questionnaires were distributed through Google Forms. A comprehensive list of 44 factors concerning student performance was formulated depending on results acquired from existing literature, technical papers, and blogs. Later, skillful responses for these factors were collected from 42 educational professionals. The fuzzy Delphi screening or evaluation phase consists of three constituent steps including: (i) conversion of judgments into estimates, (ii) defuzzification using Graded Mean Integration Representation (GMIR), and (iii) screening of the critical factors according to the threshold value. The threshold can be subjectively set according to the mean or geometric mean of all evaluation factors [45]. By referring to the geometric mean of all 44 candidate evaluation factors, the threshold value was subjectively set to 3.37. Based on results from the Fuzzy Delphi screening process, a detailed and multidisciplinary grading system was developed. Out of 44 features, 29 features crossed the threshold mark of the grading system which was 3.37 out of 5, and were considered significant. Certain unavailable features such as Family Income and Attendance rendered the dataset with 27 features. Features such as teaching quality was thought to be entered from only our university where it was considered to be the same for each student. The Fuzzy Delphi thresholding discarded this feature as well.
