Comparison of two Normalization Procedures and implications for students
Normalization procedure 1 • Get percentile (P) of a student on the basis of 5-subject aggregate scores in board. • Determine the JEE-Main aggregate marks corresponding to percentile P at the All-India level. Regard this as the normalized board score of the student (B1). • Get JEE-Main aggregate marks (A0) of the student. • The composite marks used for drawing merit list is A1 = 0.6 A0 + 0.4 B1.
Normalization procedure 2 • Get percentile (P) of a student on the basis of 5-subject aggregate scores in board. • Determine the JEE-Main aggregate marks corresponding to percentile P from the set of aggregate marks obtained by different students of that board in JEE-Main. Regard this as the normalized board score of the student (B2). • Get JEE-Main aggregate marks (A0) of the student. • The composite marks used for drawing merit list is A2 = 0.6 A0 + 0.4 B2.
Distance of P1 And P2 From P0 for different Percentile Ranges of P0 • The Difference of P2-P0 gives more stable results across the boards compared to P1-P0, which deviates from the P0 as high as 15 P0 <= 50 >15% of Student moved from Lowest Scoring group to higher Scoring groups 50> P0 <=75 Almost 10% of Student moved from this group to either higher Scoring Groups or Lower Scoring Group
Distance of P1 And P2 From P0 • Again, P2-P0 shows lesser variation compared to P1-P0 75> P0 <=95 P0 >= 95
Distribution of Students in Four Percentile Groups under P0, P1 and P2 % of Board Students Under Different Percentile Ranges – P0 % of Board Students Under Different Percentile Ranges – P1 % of Board Students Under Different Percentile Ranges – P2
Migration of Students under P1 And P2 From P0 % of Board Students Under Different Percentile Ranges – P0 % of Board Students Shifting from P0, under Procedure P1 % of Board Students Shifting from P0, under Procedure P2
Distance of P2 From P1 Difference between P2 and P1 (% of students in different Percentiles groups of P0)
How Students at Same Score (P0) in AIEEE Move Under P1 and P2 Change in Rank under Procedure P1 Shared this Rank (27493) in P0 AM AM AP AP BR BR CBSE CBSE CISC CISC GT GT HP HP KK KK KL KL MG MG MP MP MR MR MR MR RJ RJ TN TN UP UP Variation at either end is higher under P1 Change in Rank under Procedure P2 Shared this Rank (27493) in P0
In 2012, 19 Students (6 from AP, 10 from CBSE, 2 from Kerala and 1 from Rajasthan) • AIEEE Aggregate Score 130 • Board Specific Percentile Score 93
Actual Performance of CBSE Students in AIEEE 2012 [Matched Cases] • 39.58 of all AIEEE candidates are CBSE students. • However, this groups constitutes • 30.19 of the top 100 AIEEE rank holders, • 32.50 of the top 1,000 AIEEE rank holders, • 36.11 of the top 10,000 AIEEE rank holders, • 40.75 of the top 100,000 AIEEE rank holders.
