• Key Concepts: 
  Mean dispersion is a statistical measure used in Quality Management (QM) in SAP to measure the spread of data points around the mean. It is calculated by taking the average of the squared differences between each data point and the mean. This measure is used to determine how much variation exists in a set of data points. 
  
  How to use it: 
  Mean dispersion can be used to identify outliers in a dataset, as well as to compare different datasets. In SAP, it can be used to compare different batches of products or services, or to compare different suppliers. It can also be used to identify trends in data over time. 
  
  Tips & Tricks: 
  When using mean dispersion, it is important to remember that it is only one measure of variation and should not be used as the sole indicator of quality. Additionally, it is important to consider other factors such as standard deviation and range when evaluating data. 
  
  Related Information: 
  Mean dispersion is closely related to other statistical measures such as standard deviation and range. It is also related to other Quality Management (QM) concepts such as process capability and control charts.
