Abstract : This thesis recommends certain changes in the procedures and formatting of Military Standard 414 (Sampling Procedures and Tables for Inspection by Variables for Percent Defective) to bring its presentation in parallel with Military Standard 105D (Sampling Procedures and Tables for Inspection by Attributes) and to make the variables standard easier to use. The procedural changes involve eliminating the Form 1 procedure of the present standard and eliminating the average range method of estimating the lot standard deviation. The format changes involve relabeling the inspection levels, regrouping the lot size ranges, and relabeling the sample size code letters. Additions to the switching procedures for tightened and reduced inspection are also suggested. (Author)
