[quote=\"Verysuperkiasu\"]Been trying to find from the web the average mean for the eng, chinese, math & science & their SDs for year 2010 and 2009 but to no avail. Are they ever disclosed? Anyone knows?
I hazard to guess these are as follows:
EL mean = 77, SD = 9
CL mean = 72, SD = 12
MA mean = 61, SD = 17
SC mean = 66, SD = 14
These are the rounded up numbers for NYPS mainstream (excl GEP) for 2010 prelim and I know a number of people whose prelim t-scores are similar to actual PSLE t-score, +/- very little, and these people has been very consistent over the years, at least about 15 of them
Do you happen to have the numbers for 2011 prelim ?[/quote]sorry no, but i think it is a good guesstimate for any years ...... the fluctuation could be just +/- very few marks, based on observation over the years -
This is the figures supplied by Crazydad on the T score thread for 2009.
CL: Mean = 78, StdDev = 10
EL: Mean = 73, StdDev = 11
Math : Mean = 63, StdDev = 9
Sci : Mean = 67, StdDev = 12
He based it on the 2007 figures with similar style to 2009 ie difficult math, easy Chines and tricky Science. Sound familiar right ?
But the SD for math is way too low, and may end up giving a very false t score for math. -

sorry no, but i think it is a good guesstimate for any years ā¦ the fluctuation could be just +/- very few marks, based on observation over the years[/quote]
EL = 50 + 10 (100-77)/9 = 76
CL = 50 + 10 (100-72)/12 = 73
MA = 50 + 10 (100-61)/17 = 73
SC = 50 + 10 (100-66)/14 = 74
T-Score = 296
I used that to compute & got 296 for max score for 2011, is it too high ? seems out of reach, did I compute wrongly ā¦ -
verykiasu2010:
from a statistical viewpoint, it is very unlikely that the T score for a single school matches the T score for the national level. Nanyang is also a school famed for giving out tough questions, tougher than the national level. If there is a such a case where the T score of a student at Nanyang matches the PSLE T score, it should not be construed as a correlation of the school's standard matching that of the national standard, rather, there was a change in the student's ability for the prelims and the PSLE, due to specific preparation work.

Aiyo. Weather v hot hor ..... Hope the markers are in the good mood ...
:xedfingers:
aiyo.. the things that a mother need to worry about nowadays... :rotflmao:

anyway.. better not laugh too hard.. the marker might be marking dd's script right now.. :nailbite: -
I wandered why this thread active when PSLE all over ...
Now its the time for parents to :nailbite:
worrying about the weather, the feng shui of the marking centres, the numerlogy of the teachers name,
Chill :celebrate: Mummies and Daddies... -
Overall it was not difficult.
:rahrah: -
Haha, so many things to worry about even though exams are over.. Wonder if i would get my target (255)... I felt like i flunked my Science. Ahhhh. Do they mark English, Maths , Science, MT, HMT on different days? Like Monday for English, Tuesday for Maths ... etc etc. ? :roll:

Not all schools is 200. Dunman and Hwa Chong is 240, unless ur DS applied for another school.vlim:
the score is it confirmed confirmed to be 200??.. :roll:
Yes, I confirmed it is 200. But my boy can be unpredictable. -

Wanted to post a reply earlier, but was shopping, then conveniently forgot.
If the same set of teacher mark for all the 4 days, then 100+ teachers should be enough per subject, ie if one teacher marks 100 papers per day as per ur assumption.ngbrdad:
Maybe 2 days to mark and 2 days to double check hor.. Just wonder they need how many teachers to mark one subject paper :roll:
Assuming around 44000 students who took PSLE.
If one teacher marks 100 papers per day also need around 500 teachers per subject.
Each teacher does not mark an entire script by himself/herself, except composition. There is specialization involved so each teacher usually marks a few questions. Experienced upper primary teachers are usually paired up to mark questions with higher level of difficulty, n vice versa. That means in one day, a teacher may mark 250-300 scripts. Mentally and physically very draining.
