MVPspc takes the Statistical Process Control Chart and Performance/Capability routines from MVPstats, and puts them in a shareware product. This makes MVPspc great for teaching SPC classes. What makes MVPspc so wonderful? Here are some of the unique features:

  • MVPspc uses simple text file input. Data can be copied and pasted directly from a Spreadsheet into MVPspc.
  • MVPspc can take data structured in dozens of different formats. For example:
    • A variable can be in a single column, where samples can be selected using another variable, a constant sample size, or for use in an individuals chart.
    • Sample data can also be entered in a rows, where each row represents a different sample.
    • Multiple variables can be in multiple columns, or in a single columns with a grouping variable.
  • Control limits may be generated in numerous ways. For example, a Range chart can use the average range, the median range, the average standard deviation, the median standard deviation, the average variance, the average moving range of the ranges, the median moving range of the ranges, the standard deviation of the ranges, or from a know standard deviation. This software is the most flexible to generate control limits -- giving you power that you will not find elsewhere.
