Type I and II Errors  Control charts are not perfect tools for detecting shifts in the process distribution because they are based on sampling distributions. Two types of error are possible with the use of control charts.  Type I error occurs when the employee concludes that the process is out of control based on a sample result that falls outside the control limits, when in fact it was due to pure randomness.  Type II error occurs when the employee concludes that the process is in control and only randomness is present, when actually the process is out of statistical control. © 2007 Pearson Education
