Question

Accepted Answer

SPC stands for Statistical Process Control, a method used to monitor and control processes. One sample z test is a statistical test used to determine if a sample mean is significantly different from a known population mean.

SPC involves using statistical tools to monitor and control processes to ensure they are operating within acceptable limits.
One sample z test is used when comparing a sample mean to a known population mean, typically when the population standard deviation is known.
In SPC, control charts are commonly used to visually display process data and identify any trends or patterns that may indicate a process is out of control.
One sample z test calculates a z-score to determine if the sample mean is significantly different from the population mean, based on a specified level of significance.
Both SPC and one sample z test are important tools in quality management to ensure processes are consistent and meet quality standards.
