It quantifies ATAR history trends since 2001, compares 2022 results with 2021 and long-term averages, and highlights course-level achievements and state rankings. The talk explains key statistics terms (mean, standard deviation, school mean expectations, z-scores) and applies them to 2-unit course success, using example calculations and a Z-score comparison table to interpret school performance.","NUTURING SCHOLAR-SPORTSMEN SINCE 1883  \nHSC Results 2022  \nPresentation to P & C  \nBy Dr K. A. Jaggar, March 13 2023  \nThe League Tables in the Media  \n􀂃 HSC rankings published in newspapers follow a basic formula:  \n= (Band 6/E4s earned ÷ Number of papers sat by students) x 100  \n􀂃 To get in Top 10 in the state, a school would need approx . 50% of Band 6s .  \n􀂃 No acknowledgement of cohort size OR difficulty of courses attempted. Our target is 600 Band 6s. This year we only achieved 539. Rank 11.  \n􀂃 We have very large number of boys in harder courses . Hence, it is difficult to get to 50% Band 6s.  \n‒ Mathematics Extension 1 (162 boys)  \n‒ Extension 2 (118 boys)  \n‒ English Advanced (193 boys)  \n‒ Physics (118 boys), Chemistry (123 boys)  \n􀂃 Since 2019 – reduced ability to plagiarise and memorise others’ responses  \n􀂃 We are working hard on our weaknesses as identified by our RAP analyses and internal data (quantitative and qualitative) .

Each band has a width of one standard deviation .  \n􀂃 Mean (μ) is the sum of all the numbers in the set (candidates’ scores in an HSC course), divided by the numbers in the set (number of candidates) .  \nSBHS’s expected mean  \nfor 2 unit courses  \nExplanation of Statistics Terms Used (Cont’d)  \n􀂃 School standard-As 84% of scores fall below one standard deviation above the mean, we expect our school’s mean in two-unit courses only, to be at the level of at least one standard deviation above the mean .  \n􀂃 Due to the scaling effects, as demonstrated later in the presentation, a target HSC mark for a two-unit course is 87, because any lower and the scaled score per unit x by 10 units would not amount to 371 or 90 ATAR.  \nExplanation of Statistics Terms Used (Cont’d)  \n􀂃 Z score for an HSC course is the school mean minus the state mean divided by the ","cbCaiht8xsIUjsUN","https://ap.wps.com/l/cbCaiht8xsIUjsUN","pdf",737970,1,46,"English","en",105,"# HSC Results 2022\n## Presentation to P & C\n## The League Tables in the Media\n## SBHS ATAR History\n## HSC Results for Class of 2022\n## SBHS High Achievers in Courses -
