Section 2 provides detailed pro- cedures for the analysis and interpretation of enumerative and classificatory data. Section 3 has to do with the planning and analysis of com- parative experiments. Section 4 is devoted to consideration and exemplification of a number of important but as yet non-standard statistical techniques, and to discussion of various other special topics. An index for the material in all four sections is placed at the end of Section 4. Section 5 contains all the mathematical tables needed for application of the procedures given in Sections 1 through 4.
^This is one of a group of handbooks covering the engineering information and quantitative data needed in the design, development, construc- tion, and test of military equipment which (as a group) constitute the Army Materiel Command Engineering Design Handbook.
—=» ~ PURPOSE OF HANDBOOK The Handbook on Experimental Statistics has been prepared as an aid to scientists and engi- neers engaged in Army research and develop- ment programs, and especially as a guide and ready reference for military and civilian person- nel who have responsibility for the planning and interpretation of experiments and tests relating to the performance of Army equipment in the design and developmental stages of production. An understanding of a few basic statistical concepts, as given in Chapter 1, is necesssary; otherwise each of the first four sections is largely independent of the others.
Each procedure, test, and technique described is illustrated by means of a worked example. A list of authoritative references is included, where appropriate, at the end of each chapter. Step-by-step instructions are given for attaining a stated goal, and the conditions under which a particular procedure is strictly valid are stated explicitly. An attempt is made to indicate the extent to which results ob- tained by a given procedure are valid to a good approximation when these conditions are not fully met. Alternative procedures are given for handling cases where the more standard proce- dures cannot be trusted to yield reliable results.
SCOPE AND USE OF HANDBOOK This Handbook is a collection of statistical procedures and tables. It is presented in five sections, viz: AMCP 706-110, Section 1, Basic Concepts and Analysis of Measurement Data (Chapters 1-6) AMCP 706-111, Section 2, Analysis of Enu- merative and Classificatory Data (Chapters 7-10) The Handbook is intended for the user with an engineering background who, although he has an occasional need for statistical techniques, does not have the time or inclination to become an ex- pert on statistical theory and methodology.
AMCP 706-112, Section 3, Planning and Analysis of Comparative Experiments (Chapters 11-14) AMCP 706-113, Section 4, Special Topics (Chapters 15-23) The Handbook has been written with three types of users in mind. The first is the person who has had a course or two in statistics, and who may even have had some practical experi- ence in applying statistical methods in the past, but who does not have statistical ideas and tech- niques at his fingertips. For him, the Handbook will provide a ready reference source of once familiar ideas and techniques.
The second is the AMCP 706-114, Section 5, Tables Section 1 provides an elementary introduc- tion to basic statistical concepts and furnishes full details on standard statistical techniques for the analysis and interpretation of measure- iti
