With Business Statistics you can easily and instantly eliminate all zeros in any range of values (zeros arise because of holidays, no data, missing data) and quickly set upper and lower acceptance boundary limits. Boundaries allow you to calculate only values that lie within an acceptable range.

Example 1. Process Control: A company analyses moisture content of dried lumber every hour. Today several tests are showing zeros because of a power failure, and some results are clearly low as the voltage dropped to zero. To obtain a valid measure of moisture content statistics for the consignment the user copies test data into the Average column, sets the program to eliminate all zero values and enters the lower limit of moisture content to accept in the calculations.
