## All About T-Score

### Re: All About T-Score

At the beginning of this thread, CrazyDad kindly came out with a formula to calculate T-scores using means and standard deviations. But that was based on stats of ard 5 years ago. I find that very enlightening. It revealed that scoring for Maths plays an impt part in getting high T-scores at least during those years.

I wonder if it is still the case now. Does anyone has info?

What is the mean and standard deviation for psle 2013?

From this thread, looks like different subject have weightage to the overall score.

Still dun have a clear idea about T-score calculation. MOE isn't that transparent as far as I know. Unless I missed something? Anyone can summarize in in post?

### Re: All About T-Score

I have been reading people writing that "it is impossible for two students to have the same t-score in the moe's computer since there are infinite decimal points behind the actual t-scores"

I wonder how true is this...

As far as I understand, as long as some students get the same scores for all the subjects they took in psle, they will have the same t-scores (no matter how many decimal points moe wants to include in the t-score) and isn't really that low probability that two or more students will have the same scores for all 4 subjects they took. Because they only take 4 subjects and there are 40,000 students taking psle in each batch....

I tried this calculator, putting my dd's prelim results and the aggregate I got is almost the same as her psle score! AmazingJarol Lo wrote:I find that this link is useful.
