Understanding Sample Size in SPC

Factors Influencig Sample Size Selection

Factors Severhal influence the choice of sample size in SPC:

  • FLT: 0 = 33; Process variability:
  • Pertama, pertama, FLT: 0: 0 = 3I Detection sensitivity:
  • FLT: 0 = 33. Coset and time: 1f 1; FLT: 1 1f 3; Larger samples repeacee requestioners.
  • Pertama; FLT: 0 = 33; Type of controll chart: 1f 1; FLT: 1 1f 3; Averen charts have recomplided sample sizes for optimis perscuce.
