LOG-NORMAL DISTRIBUTION ANALYSIS OF THE AEROSPACE RESEARCH PROJECTS.
Abstract
The purpose of the study is to determine whether OAR research projects follow the log-normal distribution pattern found by B. V. Dean for the U. S. Army and Navy research project costs. The log-normal probability distribution would provide a model to measure research management performance which could be used to evaluate management efficiency and aid in improving the research planning and budgeting process. A simple factor analysis with orthogonal rotations performed on five of OAR's work unit parameters - fiscal year dollars, man years, total dollars, total duration and annual rate - indicated that fiscal year dollars was a highly significant factor. Therefore, 1968 and 1969 costs for 18 ORA, 48 ARL, and 289 AFCRL work units were analyzed and compared to log-normal probability distributions with the same means and standard deviations as the data. The goodness of fit in each case was checked by plotting the data on log-normal probability paper and also by comparison with appropriate chi-square statistics. The goodness of fit is discussed and recommendations for further study of the data are made. (Author)
