Sample size: number nahi badalta, bharosa badalta hai.
Doosre naam: sample size, number of observations, n, how many trades.
Is page ke kuch hisse abhi English mein hain.
Formula
The plausible range around a measured rate narrows roughly in proportion to the square root of the sample size. Quadrupling the observations halves the width.
Ise kaise padhein
Ek hi number bahut kam observations se bhi nikal sakta hai aur bahut zyada se bhi. Number dono baar wahi dikhega — farak yeh hai ki asli value uske kitne paas hone ki umeed ki ja sakti hai.
Isliye sample size bataye bina koi bhi rate adhoora hai. Woh ek number toh deta hai, lekin us number par kitna khada hua ja sakta hai, yeh nahi batata.
Yeh kya nahi batata
Bahut se observations hone ka matlab yeh nahi ki woh swatantra hain. Overlapping khidkiyan ginti toh badha deti hain, lekin nayi jaankari nahi jodti.
Isi tarah ek hi move par kai positions ek jaisi ginti hain, jabki woh ek hi ghatna hain. Aur ek hi data par bahut se rules aazmane par kuch ka acha nikalna apne aap hi tay hai.
Jude hue concepts
Ek darjan mauke lagbhag kuch bhi saabit nahi karte.
Bahut kam mauko par naapa gaya hit rate ek bahut chaude anishchitta ke daayre ke saath aata hai — itna chauda ki usme sab aa jaata hai.
