A translation of an elementary statistics text into the context of weapon-system analysis. It is designed to supplement the statistical training of maintenance personnel of the Reports and Analysis section at the base level. Most of the examples are from SACR 66-7, but the methods are applicable to data generated by other major Commands. Since most maintenance measures are frequency counts, emphasis is on dealing with this kind of data. Three principal maintenance problems are considered 1 how alert is affecting the break-rate 2 what effect the 100-hour periodic is having on subsequent missions and 3 whether any bomb-nav systems are deteriorating. The answers demonstrate the use of the chi-square test and simple analysis of variance.
