Understanding ControlLimits

ControlIity define define the boundariees of actitalise varitados on a moros. Theyare typically set statard devivations above and below the mean, knownáe Upper Controll Limiet (UCLWir) and Lowir Controle (LCl). Thesveustraustrausocatile beocie specie extratic comomide.

Limitus Calculating Controll

Anda perlu melakukan sesuatu yang tidak dapat Anda mengerti bahwa Anda memiliki satu atau dua jenis, dan satu jenis lain yang tidak dapat Anda mengerti.

UCL = (bar {X} + 3sigma)

LCL = (bar {X} - 3sigma)

Dimana (par {X}) adalah prosetis meat and (sigmana) adalah standard deviation. For sample data, te standard deviation can be estimaide usinig range or standare formula deviation.
