Abstract:

This is the fifth volume of this report.

The six volumes of this report are: Volume 1. Overview; Volume 2. Experiment Design; Volume 3. Data Extraction; Volume 4. Data Reduction; Volume 5. Data Analysis; Volume 6. Data Display T

This volume shows how to analyze a performance parameter from a single test, and from multiple tests conducted at selected combinations of levels of variable conditions. Single and multiple tests can analyzed in any of four ways: estimation with known precision, acceptance tests, comparison tests, and tests to determine if a variable condition is a factor. Formulas for these analyses are provided. The formulas are incorporated in an interactive FORTRAN program that can be implemented by either a shell script or an operator. In all cases, dependence between trials is estimated by a first-order Markov chain. Performance parameters are analyzed from multiple tests by, first, pooling trials of tests, then means of tests, and, finally, means of levels of a selected variable condition.
