An example approach to the analysis of data from the chemistry, biology, and inventory files of the antimalaria drug development program at the Walter Reed Army Institute of Research is presented. A general approach to the analysis of data from large files based on the organization of those files is discussed. (2 references) (Author/NH)

Advocates a simplified procedure for assessing the validity of experimental data. Suggests using the range of the results of a limited number of repeated measurements to obtain confidence limits about the probable over-all average of repeating the same procedure a great many times.
