ASTM D4686-91(1998)

1.1 This guide gives the rudiments of identification of some of the most common and useful frequency distributions. It does not give rigorous identification. To achieve exactitude, the procedures similar to those given by Shapiro should be used.

1.2 This guide provides a key to identify frequency distributions.

1.3 This guide gives ways to select the proper transformation to use to transform a particular set of data to one which can be modeled by the normal distribution, if such a transformation can be found at all.

1.4 This guide includes the following topics:

Topic Title Section Scope 1 Referenced Documents 2 Terminology 3 Significance and Use 4 Key to Distributions 5 Binomial Frequency Distribution 6 Poisson Frequency Distribution 7 Normal Frequency Distribution 8 Sample Average Distribution 9 Other Distributions 10 Transformations of Data 11
