The purpose of this document is to provide guidelines for planning, analyzing data, and reporting the uncertainty of experiments. Appropriate terms are defined and statistically based procedures and formulae are recommended for evaluating experimental data related to HVAC&R. Numerous examples are provided to illustrate analysis of experimental data.

Although this guideline addresses many of the ways in which statistics are used in HVAC&R applications, it should not be considered a comprehensive statistical text. An attempt has been made to provide sufficient background and references for the statistics used in this guideline.
