Measurement Systems Analysis For Binary Data
Test Effectiveness Calculator
Version 1.0, August 2002
Introduction
Welcome to the Measurement Precision Calculator. This utility is intended to
perform the calculations for Measurement Precision Studies as described
in the IPC test method IPC-TM 1.8.
This unility is useful for situations where the measurement data is recorded
in binary format,, such as pass/fail or go/no-go.
Please refer to the test method before beginning the measurement precision study.
The test method defines the terms and equations used in detail.
Refer to the User Guide for further detailed instructions.
This workbook includes the following
- A blank spreadsheet to enter measurements
- A spreadsheet with example data
- A form for manual data entry, if desired.
The test data should be entered into the yellow areas on the
data entry spreadsheet. Code results as "A" and "R".
This is a beta version of this software.
Your comments and suggestions would be appreciated.
If you have any questions, please contact:
