Karaniwang Pamamahagi

Ang normal na pamamahagi ay isang tuluy-tuloy na pamamahagi ng posibilidad. Tinatawag din itong pamamahagi ng Gaussian.

Ang normal na function ng density ng pamamahagi f (z) ay tinatawag na Bell Curve sapagkat mayroon itong hugis na kahawig ng kampanilya.

Ginagamit ang karaniwang normal na talahanayan ng pamamahagi upang hanapin ang lugar sa ilalim ng pagpapaandar ng f ( z ) upang makita ang posibilidad ng isang tinukoy na saklaw ng pamamahagi.

Karaniwang pagpapaandar ng pamamahagi

Kapag ang random variable X ay may normal na pamamahagi,

Ang posibilidad ng pagpapaandar ng density at pinagsama-samang pag-andar ng pamamahagi ng normal na pamamahagi:

 

Pag-andar ng density ng probabilidad (pdf)

Ang pag-andar ng density density ay ibinibigay ng:

f_ {X} (x) = \ frac {1} {\ sigma \ sqrt {2 \ pi}} e ^ {- \ frac {(x- \ mu) ^ 2} {2 \ sigma ^ 2}}

Ang X ay ang random variable.

Ang μ ay ang ibig sabihin ng halaga.

Ang σ ay ang karaniwang halaga ng paglihis (std).

e = 2.7182818 ... pare-pareho.

π = 3.1415926 ... pare-pareho.

 

Cumulative function ng pamamahagi

Ang pinagsamang pagpapaandar na pamamahagi ay ibinibigay ng:

F_ {X} (x) = \ frac {1} {\ sigma \ sqrt {2 \ pi}} \ int _ {- \ infty} ^ {x} e ^ {- \ frac {(y- \ mu) ^ 2 } {2 \ sigma ^ 2}} dy

Ang X ay ang random variable.

Ang μ ay ang ibig sabihin ng halaga.

Ang σ ay ang karaniwang halaga ng paglihis (std).

e = 2.7182818 ... pare-pareho.

π = 3.1415926 ... pare-pareho.
