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

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

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.

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

Very Happy:D:D

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!
