SD (Standard Deviation)
What does Standard Deviation actually mean?
What is it used for?
How does it help us in improving our times?

Re: SD (Standard Deviation)
Standard deviation is the measure of the spread of your cubing time, it means it measures the spread of number of tries in your average time trial. Mas madali explain kung may graph hehehe
Re: SD (Standard Deviation)
I'll make it simple for you. If your SD has a bigger number, that means your average is much closer to luck, its not stable. If you get a smaller number, that means your stable in your times.
Re: SD (Standard Deviation)
in the series of numbers :
1 1 1 1 1 1 1 1 1
the standard deviation is at it's minimum. (the difference between each number in the series is zero)
The numbers are flawlessly consistent.
In this series, however :
1 999 2 3 87 64 2 1 43
it is huge. The difference between them are enormous, thus, illustrating the numbers in the series as inconsistent.
Standard Deviation, then, is simply the parameter that identifies the consistency of your solving times. As defined by John Cañares, it does quantify your luck when looking at your average. ü

Re: SD (Standard Deviation)
14 pa lang kc c jetty, hehe, di nya kagad magets.. basta in short SD ay parang rank mo in solving cubes.. buti ka pa nga mabilis na tlga u magsolve.. hehe, bibilis din ako.. tnx nga pla jet ako ung nagpaturo sau magsolve nung 2x2x2 nung 3rd cube meet.. hehe, simple lang pla un

Re: SD (Standard Deviation)
stat major po ako dati bago ako naging math major ngaun
at ang pagkakaalala ko sa SD
un na nga
sinabi na ng iba nating cubers
dispersion o spread ng data (or tym in this case)
mas malapit sa zero, mas "consistent"
mas malayo sa zero, mas madalas ung "luck"
sana makatulong!

no prob man! anytime.
thanks guys for helping me understand SD.
Re: SD (Standard Deviation)
aw. i get SD of 2 to 3 seconds. normally.

Re: SD (Standard Deviation)
ako sobrang laki lagi ng sd.. hehe madistract lang kasi ako ng konti, ang laking effect na.. mabilis pa naman ako madistract.. hehe
Re: SD (Standard Deviation)
minsan, ngssound3p ako(mp3) hbng kmkuha ng average. para bawas distraction. hehehe
