WBA Specialized Lectures (on demand) - Siebel Institute of Technology


Learn more about how statistics can be used to monitor and maintain the quality of raw materials and finished products.


Variability, Statistics, Random, Limits, Variance, Sigma, Control, Chart, Hypotheses


Random variability follows systematic rules. This is what allows statistics to be a practical tool in quality control. Statistics do not make decisions for you. Rather, statistics measure the risks that you would be taking whenever you draw any conclusions. Do you really need to intervene and make adjustments or is the observed variability within acceptable limits? The content expert will guide you through the maze of data that you have collected.

Learning Objectives

  • Define basic terms related to statistics
  • Describe the “power” of averaging
  • Explain the types of Statistical errors
  • State the proper hypotheses
  • Use and interpret X-Bar Charts
