ASTM Committee developing proposed non-parametric standard.
Press Release Summary:
October 3, 2011 - Interested parties are invited to join in development of proposed standard ASTM WK32565, Guide for the Use of Non-Parametric Statistical Methods. Non-parametric methods are useful to anyone using data analysis tools when nature of underlying distribution is not known, when attribute type data exists, and when just a small sample is available to compare 2 or more groups and show significance when sizeable difference can be expected.

Press release date: September 27, 2011
o When the nature of the underlying distribution is not known;
o When attribute type data exists;
o When just a small sample is available, to compare two or more groups and show significance when a sizeable difference can be expected;
o To predict where the next several observations will fall with respect to a present sample; and
o To estimate some proportion of a population process output based on the sample values from a current sample. Luko says the task group developing ASTM WK32565 is interested in user applications involving smaller sample sizes and how this situation is currently handled.
